Netbeans 7.2 not starting - netbeans

I recently installed Netbeans 7.2 beta and it worked fine. Then I installed Netbeans 7.2 final release on top of beta and during the installation, Netbeans 7.1 and Netbeans 7.12 were there. Now when I launch Netbeans, it does not go beyond "loading modules" stage. Simply the Netbeans screen disappear few seconds after the launch. Then I did the following.
Uninstalled all the Netbeans versions and re-installed Netbeans 7.2
Deleted AppData/Netbeans folder
Deleted User/.nbi folder
Searched the registry and deleted Netbeans related entries. (But only one entry was found)
Deleted Netbeans Folder in Program Files folder.
Uninstalled and Re-installed in a separate drive.
Uninstalled and Re-installed under another user account.
None of the above worked, the only thing I did not try was to re-install the Windows XP operating system.
It there any option to try before re-installing the operating system?


I was having the same problem .... with netbeans 7.2 ,go to user/appdata/roaming/7.2/modules/ and delete all the jar files except docs,ext,locale folders ... and start the ide again... basically the problem betides when u update the ide after update when u start the ide it stuck to the loading module phase.


First of all, you need to check proper version of JDK is installed.
Netbeans 7.2 requires JDK 1.7, not 1.8.
You can check {Netbeans Install Path}/etc/netbeans.conf. There find netbeans_jdkhome and its value. Make sure you install JDK1.7 and this line netbeans_jdkhome="C:\Program Files\Java\jdk1.7.0_25" for example.
If not, change the value to proper installation path.


That's some stability issue with NetBeans 7.2
Just Kill and Restart the IDE and it should be fine.


Make sure that right JDK directory chosen in the installation wizard if you not sure you can change it from
C:\Program Files\NetBeans {netbeans version}\etc
you will see a file which is
netbeans.conf
edit it(I am using Notepad++ for that)
At the bottom of the file, you will see a line
netbeans_jdkhome="C:\Program Files\Java\{jdk directory you want}"
make sure it is valid JDK and it is JDK, not JRE


I had the same problem, make sure you have the required JDK version configured during the installation process.


First tried everything to no avail, finally I had to uninstall NetBeans 7, then install NetBeans 8, which also aligned with my JDK 8. This resolved the issue for me. Hope this helps others.


Ah, finally this worked with me on version 11.3, delete this folder, then run the program again
C:\Users\Dell\AppData\Roaming\NetBeans
here my main username is Dell, yours can be different ofcourse


I found out in my Windows installation of Apache Netbeans 12.4, the file 'tctracker.properties' in 'C:\Users\user\AppData\Roaming\NetBeans\12.4\config\Preferences\org\netbeans\core\windows' was filled with null values. I fixed the issue with letting netbeans generate a new file by moving this '12.4' directory to somewhere else on the disk, starting Netbeans, letting it generate a new 'tctracker.properties'-file, stop it, replace the corrupt file in with this newly generated file and put the '12.4' directory back in place.

Mac OS: can't install Eclipse [duplicate]

I have formatted my Mac due to some storage issues. Before this, I used Eclipse in a proper way. Now i have installed the JDK
Then, i have installed Java
Until now everything seems to be correct but when I open the Eclipse installer...
What can I do to fix this? I need to work with this the soon as possible.
Thanks

Eclipse on macOS will not start with Java 14 installed, this is being tracked in Eclipse bug 561273.
Installing Java 8 as well does not help. You need to remove the Java 14 install. You could use the Java 13.0.2 release instead.
Eclipse have determined that the root cause of this issue is a change in Java 14 which is described in this bug report JDK-8238225. The fix for this should be in Java 14.0.1
Update: Eclipse runs fine with Oracle Java 14.0.1 so the issue has been fixed.

I also asked this question which was closed, that's why I answer what I have found out: Eclipse will not install on Mac OS Catalina 10.15.4, saying the above error message
Failed to create the Java Virtual Machine.
Deinstalling jdk and install an older one wouldn't help on its own because Eclipse is refusing to install in the first place (as mentioned above). What I have done:
i´ve installed an JDK with boost (you can try several, mine worked with Version 13)
I edited the installer:
Download the dmg file
convert the dmg-file with "hdiutil convert /dev/disk3s1 -format UDRW -o devimage"
mount the converted dmg-file with: "hdiutil attach -owners on devimage.dmg -shadow"
Edit the /Volumes/Eclipse/Eclipse.app/Contents/Info.plist: there is a section which is commented and there you can try the jdk version. You have to give the full path to the java executable, for example:
<string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/bin/java</string>
Then my eclipse started from the (already) mounted Eclipse image without complaining

I had the same issue myself a while back. In your Eclipsepedia it provided an example of what the eclipse.ini file looks like when your trying to specify a JVM. So just change the eclipse.ini file and then make sure that you have all of the correct documents in that path to match the example.

Can't create project on Netbeans 8.2

I have windows 10 OS, I just downloaded JDK 9, and Netbeans 8.2 version with All features. When I want to create (Java) project, it just can't do it. Doesn't give me an error or something, just this blank screen.
What could be problem here, so I can't create any project ?

EDIT:
The solution is to install JDK 8, as JDK 9 and beyond are currently not supported.
If however, you already have installed JDK 8, then kindly follow the steps outlined below.
The reason is that there is a conflict with the base JDK that NetBeans starts with. You have to set it to a lower version.
Go to the folder "C:\Program Files\NetBeans 8.2\etc", or wherever NetBeans is installed.
Open the netbeans.conf file.
Locate netbeans_jdkhome and replace the JDK path there with "C:\Program Files\Java\jdk1.8.0_152", or wherever your JDK is installed. Be sure to use the right path, or you will run into problems. Here, JDK 1.8.0_152 is installed.
Save the file, and restart NetBeans. It worked for me, should do for you too.

You can solve your problem by deleting folder JDK-9.
Restart Netbeans.
It will give you a message if you want to use the default version of JDK.
Press yes or ok.
Or you can remove JDK-9 from your pc and install JDK-8.

As the other people said, NetBeans is always going to use the latest version of JDK installed (currently JDK9) which is not working with NetBeans 8.2 and is causing problems as you guys mentioned.
You can solve this problem by forcing NetBeans to use JDK8 instead of deleting JDK9!
You just have to edit netbeans.conf file:
MacOS /Applications/NetBeans/NetBeans8.2.app/Contents/Resources/NetBeans/etc
Windows C:\Program Files\NetBeans 8.2\etc\
Open netbeans.conf with your favourite editor and find this line: netbeans_jdkhome="/path/to/jdk"
Remove # sign in front of it and modify it by typing your desired JDK version (JDK8) home location.
Im not sure why is JDK9 not working with NetBeans8.2, but if I found out I will write it here...
Default JDK locations:
Mac OS ↴
/Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home
Windows ↴
C:\Program Files\Java\jdk1.8.0_152
I've used jdk1.8.0_152 as example

I had the same problem I installed NetBeans 8.2 on macOS High Sierra, and by default settings, NetBeans will work with the latest JDK release (currently JDK 9).
What I did was forcing NetBeans to use JDK 8, you must config your netbeans.conf file, you can find it on:
/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/etc/netbeans.conf
You need to uncomment and update your path to JDK, you will find yours at:
/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
Just save it, restart NetBeans and you are done!

If you run in linux, open file netbeans.conf using nano or anything else.
nano netbeans-8.2/etc/netbeans.conf
and edit jdkhome or directory for jdk
netbeans_jdkhome="/usr/lib/jvm/java-1.8.0-openjdk-amd64"
you can check your jdk version with
java -version
or
ls /usr/lib/jvm

Java SE Development Kit 9 is not compatible with the Netbeans IDE 8.2.
My Solution:
Delete the current JDK 9
Install this previous trust version of JDK: JDK 8
Modify the following file: \Program Files\NetBeans
8.2\etc\netbeans.conf to the given folder path of the newly installed JDK 8: netbeans_jdkhome="C:\Program
Files\Java\jdk1.8.0_151" (example)

Faced same issue with jdk 10. While installing netbeans prompted for jdk default location was taken as jdk 10. This was the issue, it should be jdk8 (1.8).
Close Netbeans
Open below file
C:\Program Files\NetBeans 8.2\etc\netbeans.conf
Comment jdkhome line jdk9 or jdk10 with # sign:
# netbeans_jdkhome="C:\Program Files\Java\jdk-10.0.1"
Add new jdkhome line for jdk8:
netbeans_jdkhome="C:\Program Files\Java\jdk1.8.0_171"
Start Netbeans
Note: If the above .conf file is not editable, then use Administrator mode. I use Notepad++, it prompted for restarting Notepad++ in Administrator mode, then save worked fine.

I had the same issue,
Quit Netbeans.
Delete the JDK9 file in : /Library/Java/JavaVirtualMachines
Install the JDK8 : Download link
Good luck :)

#ubuntu 18.04
sudo apt install openjdk-8-jdk
then
sudo update-alternatives --config java

Press <enter> to keep the current choice[*], or type selection number:
choose java 8 then restart netbeans
Done

Yes it s working: remove the path of jdk 9.0 and uninstall this from Cantroll panel instead install jdk 8version and set it's path, it is working easily with netbean 8.2.

I tried setting netbeans_jdkhome="/path/to/jdk-9.0.4" in netbeans.config of "C:\Program Files\NetBeans8.2\etc" in Windows 10. It shows a notification "Unexpected Exception".

For anyone that wants to download jdk 8 without an oracle account: https://download.oracle.com/otn-pub/java/jdk/8u271-b09/61ae65e088624f5aaa0b1d2d801acb16/jdk-8u271-windows-x64.exe copy and paste the link. Jdk 15 didn't work for me so i tried using jdk 8 and it worked.

Open notepad as administrator(right click on it then click run as administrator)
Open the following document from Netbeans directory via Notepad file->open. Make sure where it was installed.
C:\Program Files\NetBeans 8.2\etc\netbeans.conf
Add the following path;
netbeans_jdkhome="C:\Program Files\Java\jdk1.8.0_171"
Save it as netbeans.conf in the same place.
Now open the Netbeans.. Everything will work properly but you will be notified regarding jdk path in the beginning..

This is how it worked for me :
Open Netbeans - A start page will be opened automatically.
On start page you can see a tab named 'Activate Features', click on it.
Select
all plugins that are installed and appeared there.
Click on
'Activate' button. Restart the IDE. You are good to go.

PyDev not showing up in Eclipse

I just installed Eclipse Kepler (after an issue with a faulty update in Juno) and tried to install PyDev using the Install New Software option in Eclipse. Basically just following memory/online tutorials. After installing I can't see it in my Preferences pane. Any ideas why that might be so?
Thanks.
Yes, I have Java 7 installed.
UPDATE: A lot of users have suggested numerous solutions to this problem. There may be more than one correct answer below. See what helps you...

Too much!
After wasting 4 hours trying to install PyDev 3, I moved back to 2.8.2 and used the drop in technique instead of Add new software and it now works!
Download 2.8.2 from sourceforge
http://sourceforge.net/projects/pydev/files/pydev/
Uninstall PyDev.
Simply unzip the contents into the dropins folder below eclipse.
Restart eclipse.

After struggling with this problem for some days I wanted to share my solution to the problem - inspired by the above posts (kudo's to them).
My Configuration:
MacBook Air (intel) with OS X 10.9
Eclipse: Kepler SR1 installed (zip file extracted in the Applications folder)
My situation:
Tried to install PyDev via Eclipse Help --> Install new software...
Installation was succesfull, but PyDev didn't show up anywhere in Eclipse.
My solution:
In Eclipse go to Help --> Install new software...
Uncheck "Show only the latest versions of available software"
Select PyDev the usual way, but install the latest 2.x version instead of the 3.x version
Apparently PyDev 3.0 does not work with the default OS X configuration of Eclipse, Java and Python (don't exactly know why, though...)

I just figured it out.
You will need JDK rather than a JRE.
Download it here first:JDK Download
Install it.
Explore /Applications/eclipse/Eclipse.app/Contents/MacOS (where you put your Eclipse)
Open eclipse.ini
add
-vm
/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bin/java
You will change the version according to your situation.
Enjoy!

It happened to me too, but using Debian stable (wheezy, in my case).
I solved installing doing:
# apt-get install openjdk-7-jdk
After this, I checked that I had two alternatives of Java JDK:
# update-java-alternatives -l
And the output was:
java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64
java-1.7.0-openjdk-amd64 1051 /usr/lib/jvm/java-1.7.0-openjdk-amd64
Finally, I did:
# update-java-alternatives -s java-1.7.0-openjdk-amd64
After that, I removed pydev plugin from Eclipse, reboot Eclipse, install pydev (using Marketplace), reboot Eclipse, and now it works.

Most likely you do not have java 7 or > eclipse 3.7 installed on your machine it is a requirement of pyDev 3 see here http://pydev.blogspot.co.uk/2013/11/pydev-30.html

The PyDev.org website states (http://pydev.org/manual_101_install.html) --
"""
Important requisite
PyDev now requires java 7 in order to run. If you don't have java 7, the update
process may appear to succeed, but PyDev will simply not show in the target
installation. Please double-check if you're using a java 7 vm in
about > installation details > configuration
before trying to install PyDev.
"""
This problem started to appear in my Eclipse after I removed the Java 7 runtime from my system (because the Java code I am building needs to run on an older version of Java, but that's unrelated). After I realized that I had lost PyDev, I reinstalled Java 7 and PyDev is working fine now.
Another option would be to rollback to the previous version of PyDev that does not require Java 7, but it would require a manual installation of PyDev and I would lose the convenience of automated updates. The best way forward, it seems, to run run Eclipse on Java 7 and switch those Java projects that need to depend explicitly on Java 6 to that JDK/JRE.

How I was able to get pydev to work in mac/eclipse is download the latest JDK as mention 100 times above install it and then do the following.
open eclipse choose preferences > java > installed JREs
click on "Search..." button it will auto populate the JDK 1.7 you just installed
Click ok
have a beer!
-Cheers!

Solved.
OSX Mavericks 10.9, Eclipse Keplar 4.3.2, PyDev 3.4
Problem: PyDev not showing up under Ecplise > preferences
Solution: Download, install and point Ecplise to JDK 1.7
Unistall PyDev
Under Eclipse > preferences > Installed JREs you probably only see Java SE 6
Download and install JDK 1.7 from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
open terminal and run "/usr/libexec/java_home -v 1.7"
this will return the directory in which JDK 1.7 reside, something like /Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home
Under Eclipse > preferences > Installed JREs click "add", select "MacOS X VM", click "next"
in JRE Home paste your version of /Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home, give it a name and click "Finish"
Restart Eclipse and re-install PyDev.
Voila!

I had the same issue on Luna and found my mistake.
After checking the author in "Do you trust these certificates?" page, and I was able to successfully install pydev.
The page lets you proceed without checking it, and no error occurs and it was where I totally missed. Maybe it is useful for someone.

You can move back to 2.x.x:
Eclipse -> About Eclipse then click "Installation Details" button.
From "Installation History" tab choose last installation.
Click Revert button.
You will go back to chosen installation.

I managed to get the following to work with Eclipse IDE for Java Developers 4.4.1 Luna on OS X 10.9.5 Mavericks:
Download and install the latest version of the JDK (currently Java SE 8u25) from http://www.oracle.com/technetwork/java/javase/downloads/index.html. (Not the JRE!)
Navigate to /Applications/eclipse/Eclipse.app/Contents/MacOS (or wherever you have Eclipse installed) and open eclipse.ini.
Append the following to the bottom of the file (be sure to replace the version number with yours):
-vm
/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java
Download the latest version of PyDev (currently 3.8.0) from SourceForge at http://sourceforge.net/projects/pydev/files/pydev/.
Unzip its contents to /Applications/eclipse/dropins (or wherever you have Eclipse installed) and restart Eclipse.
Hope this helps anyone who's still having the issue. Special thanks to Mohammed Lokhandwala and braineo.

Aha , It is solved just now.I show it in the following.
First , I use MyEclipse with jdk1.8,maybe some people dont know that Eclipse (or MyEclipse) has its own jvm , what is not "jdk" you downloaded and installed and the "built-in jvm" is default. You can check this out by clicking like this " Windows-->preferences-->Java-->Installed JREs" And I found my MyEclipse used the default jdk1.6 .Then I click "add" to build path of my installed jdk1.8 .
Second , I opened the configuration file named "myeclipse.ini" and check this in the following.
binary/com.sun.java.jdk.win32.x86_64_1.6.0.u43/bin/javaw.exe
Third , I replaced it with new path . Check the following out. It is new path.
D:/jdk/java/jdk1.8/bin/javaw.exe
Last , restart it .And you can find "PyDev" in "Preference".
Happy Coding with Python!
PS：Pycharm is good,and you can get it for free if you are a student or a teacher. click here

I was experiencing the same problem using java 1.7.0_101.
Updated to 1.8.0_91 and "voilá"! PyDev finally appeared.

After trying all of the listed ways to work with 1.7 I was still seeing error message when Eclipse tried to open the editors and navigators on startup. But when I created a new project it worked. Then I tried just closing all editors and reopening them and they too work. The navigator had also set itself to working set and showed nothing. When I switched that to projects it also started working.

The same thing happened to me. This is how i fixed it.
Click on "install new software" - it's under help.
Click on " what is already installed"
Uninstall PyDev
Reinstall PyDev BUT instead of the 3.3XX version, install the latest 2.XX version (i.e click on the drop down menu and select the latest 2.XX version)
It worked for me!

So I tired many of the suggestion above, and I think what finally got it to work is instal the JDK from: http://www.oracle.com/technetwork/java/javase/downloads/index.html. You might also need to uninstall the pydev plugin and reinstall it again. But after install the JDK 8, I got the Pydev to show up under preference.

menu Help > Install New Software...
don't fill "works with" but click on Add...
In the next screen, add the update site of PyDev and PyDev Extensions:
Name : PyDev and PyDev Extensions
Location: http://pydev.org/updates
and go on...

pydev 3 is buggy! Use 2.8 and you should be fine.

I also had this problem, wanted to use python3.4 as interpreter and it wasn't compatible with pydev 2.8 so after a few trials I found out that if you install pydev 2.5 everything works fine !! (At least on Eclipse Kepler).

I know this thread is old but I thought I might contribute my solution because none of the suggestions above worked for my Mac running Yosemite [10.10.2]. I hope this will be helpful to someone else. Despite updating to the latest JDK my mac kept reporting a wrong version. It turns out the symlink was point to the old version and fixing that issue got my pydev/eclipse working.
Find out the current default Java version
Java -version
Get installed versions
/usr/libexec/java_home -V
Navigate to the following folder and delete the current symlink
cd /System/Library/Frameworks/JavaVM.framework/Versions/
rm CurrentJDK
Create a new symlink pointing it to the newer installation substituting 'new-version' with appropriate version from 2 above. i.e jdk1.8.0_40.jdk
ln -s /Library/Java/JavaVirtualMachines/<new-version>/Contents/ CurrentJDK
Confirm your default version
Java -version
Restart.
Happy coding.. :)

I had to uninstall pyDev 3 and install 2.8 to get this working with Eclipse (V 4.4) and Yosemite (V 10.10)

The easiest way is just getting http://www.liclipse.com/ which has everything setup from the start... if you don't want to go that route (as LiClipse is commercial) you may want to try to specify the java 7 install manually:
Grabbed from http://pydev.org/download.html:
Well, the main issue at this time is that PyDev requires Java 7 in order to run. So, if you don't want to support PyDev by going the LiClipse route (which is mostly a PyDev standalone plus some goodies), you may have to go through some loops to make sure that you're actually using Java 7 to run Eclipse/PyDev (as explained below).
All OSes
Make sure you download/install the latest Java 7 JRE or JDK, try restarting to see if it got it automatically.
I.e.: in help > about > installation details > configuration check if it's actually using the java 7 version you pointed at.
If it didn't get it automatically, follow the instructions from:
http://wiki.eclipse.org/Eclipse.ini to add the -vm argument to eclipse.ini on "Specifying the JVM" to specify the java 7 vm.
Note on Mac OS: You can use the command "/usr/libexec/java_home -v 1.7" to get the base path for the JVM (though you also need to append "/bin/java" to the output of said command to the -vm arg in eclipse.ini).

Solution
Using standard Eclipse installation method:
In Install New Software, Add a new site to Work With. I called my entry PyDev Old and entered the Location:
https://dl.bintray.com/fabioz/pydev/old/site.xml
That has PyDev for Eclipse versions 2.8.2 to 4.5.3
Details
I am working with Indigo (3.7) and so need a version of PyDev that is older than 3.0.0. My JDK is 7 as noted elsewhere in this question. The option for Show only the latest versions of available software is turned off.
The standard advice for getting PyDev is to use http://pydev.org/updates and turn off the only latest option. That now only lists PyDev 5.

I had the same issue!
Just update all three SWs to the latest version and it will solve the problem.
Do like this:
update Eclipse to Luna Service Release 2 (4.4.2) 64-bit, then
PyDev - Python IDE for Eclipse 5.1.2 from Eclipse Marketplace and then
download and update the Java SE Development Kit 8u92 64-bit
It should work well now!

I had the same issue in Eclipse 4.4. Had to use a previous version of PyDev. It simply seems to be a matter of using the correct Java JRE/JDK and PyDev for the version of Eclipse you're running.
From http://www.pydev.org/
Release 5.2.0
Important PyDev now requires Java 8 and Eclipse 4.5 onwards.
PyDev 4.5.5 is the last release supporting Java 7 and Eclipse 3.8.
See: update sites page (http://www.pydev.org/update_sites/index.html) for the update site of older versions of PyDev.

Oct 2016:
Installed fresh new copy of Java JDK 1.8.0_102 took care of the incompatible OSX JRE 1.6
Installed fresh copy of Eclipse Neon 4.6.1
Followed pydev manual: http://www.pydev.org/manual_101_install.html
all working fine now...

First install and setup following applications as these are mentioned in above answers:
Jave (version 8 or greater)
Eclipse(version Neon/Oxygen or greater)
PyDev in Eclipse
Now go through following steps:
Eclipse -> Window -> Perspective -> Open Perspective -> Other..
Select PyDev in the list.
Click Open.
Now you are all set.
Cheers!!!

Make sure you install the 64-bit version of Eclipse if you can. If so you should be able to use the latest version of Pydev without any problem.

Eclipse Indigo Update from SR1 to SR2

How can I update Eclipse to the newest service release SR2?
I have selected http://download.eclipse.org/releases/indigo as my only update site. At some point during the update I get the following error.

What worked for me was to just download the new eclipse package. Deleted my old eclipse installation directory and unzipped the new archive to the same location. Then I just had to set my workspace directory again and finally I had to install all plugins I previously had installed.
Only small problem was to get the proper version (x86 or x64) because I could not check which Version I had previously installed. So I 1st got x64-eclipse but on that one I couldn't got subclipse to work. The x86-version worked like a charm.
Dunno why x64-subclipse didn't worked because my suite runs on windows-x64 with a x64 jdk but I don't care for the moment because I just write x86 programs atm anyway.

I didn't change anything but it is working now. Looks like someone has finally added all missing dependencies on the update servers.

Subversive not showing up in eclipse

I am trying to install subversive for eclipse helios on windows 7. I am seeing it as installed in the installation details, but it is not showing up as a perspective and also in windows/preferences/team. Can anyone help me with this.

I fixed that issue by granting my user writing access to the eclipse installation directory (default in "Program Files" is read access).

#squig - +1
changing the directory permissions (I placed it under c:\program files\eclipse in Windows 7) caused the subversive plugin to work, after spending endless hours on trying to figure out the issue.
The lame part from Eclipse side (or Subversive side, dunno) is that no error message was shown, it appeared as if the software was installed properly. Shame.

I had exactly the same problem. But in my case the problem could not be solved be granting write access to the eclipse programm directory.
The reason was that I tried to use two versions (Mars and Neon.2) of eclipse in parallel. When I tried to install both programms into one directory in "C:\Programm Files (x86)\Eclipse" it was not possible to install plugins etc. to the newer version. Therefore I uninstalled the newer version and reinstalled it under "C:\Programm Files (x86)\Eclipse-Neon".
After this everything is fine. Even without write permissions to the programm directory.
