I downloaded Eclipse Juno and I am trying to run it for the first time. System is Win 7 Home Premium and I also downloaded JDK. I am getting the following error:
A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be
available in order to run Eclipse. No Java virtual machine was found
after searching the following locations: C:\Program
Files\eclipse\jre\bin\javaw.exe javaw.exe in your current PATH
The javaw.exe file it needs is in...
C:\Program Files\Java\jre7\bin\javaw.exe
How do I fix this problem? Thanks in advance
" A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: C:\Program Files\eclipse\jre\bin\javaw.exe javaw.exe in your current PATH "
You need to install Java JDK: http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
and then edit your path location:
Right-click on computer->properties->advanced system settings->advanced->environment variables:
Add C:\Program Files\Java\<JDK version>\bin to your PATH variable.
Also add JAVA_HOME as a system variable. I have my JAVA_HOME set to C:\Program Files\Java\jdk1.7.0_03.
When you are done, start cmd, type java, and hit enter. If you get an error that it can not be found then java is not correctly installed.
You just need to have a Java environment installed in one of the locations Eclipse looks. For Eclipse you do NOT need the full JDK.
It is enough to install a Java Runtime Environment, e.g. from java.com. This still allows you to develop against any JDK - this is just about the JVM that Eclipse needs for itself.

I have a new computer (Windows 10, 64bit) and I can't install Eclipse.
I downloaded a file called "eclipse-inst-win64.exe" and a file called "jdk-12.0.1_windows-x64_bin". When I try to open or run as and administrator the Eclipse, I recieve the following message:
"A Java Runtime Enviorment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse Installer. No Java virtual machine was found after searching the following locations:
C:\Users\USER\Downloads\eclipse-inst-win64\jre\bin\javaw.exe
javaw.exe in your current PATH".
What did I do wrong? What should I do? Thanks.
Of course, you have to install jdk FIRST. Make sure to set your JAVA_HOME system environment variable to the folder where you installt jdk-12.0.1 and add the bin folder of the jdk to the PATH environment variable. You can test your installation: open a PowerShell and execute java -version. It should display your installed version. If not, the variables are not set correct.
Eclipse gave me an error specifying that no JRE is installed while I was trying to configure Erlide in eclipse.
I added path to erlang directory in 'System Variables'. Then I installed erlang plugin for eclipse, added erlang installation directory path in Eclipse preferences and restarted Eclipse.
After restarting eclipse started giving me error about JRE.
Below steps might help you to solve your problem.
Install JDK and JRE - Here are step by step Instructions OR ANOTHER
Verify you setup JAVA_HOME and JRE_HOME and PATH into environment variable.
You can also investigate your Java version via Command Prompt:
Open a Command Prompt (Navigate to “Start” => “Run” and type “cmd”)
Then enter the following command:
java –version
If you don't see your java version you have to follow step 1 carefully again
Installed eclipse/ if already installed open the same. Here are step by step Instructions
NOTE: Make sure that you have same bits for both JDK and EClipse (32 or 64). One way is to verify in your ini file.
To develop a Java program, you need a JDK not only a JRE.
Do you have a JDK installed? Have you tried to run jar, $ set | grep "JAVA_HOME" (Linux) or C:\> set | find "JAVA_HOME" (Windows) in your command prompt to see if you have Java configured in your machine?
Once you install your JDK you need to set this environment variable.
Maybe Earlide is not compatible with your JDK 1.8, can you try with jdk 1.6

Eclipse - no Java (JRE) / (JDK) ... no virtual machine

Closed 9 years ago.
I have JRE 6 installed (can't update due to admin restrictions), but all of a sudden Eclipse won't start up. It has worked in the past. Here's the error message I'm getting:
A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations:
C:\Documents and Settings\USER\Desktop\eclipse\jre\bin\javaw.exe
javaw.exe in your cuurent PATH
If this is due to some sort of admin restrictions (nothing seems to be different from before), is there a way I can use Eclipse in another way? Perhaps without the JRE?
EDIT: jre\bin\javaw.exe does not exist. Why is it looking for it there?
Check the -vm entry in the eclipse.ini configuration file. The format is
-vm /path/to/jre/bin/javaw.exe
If this entry does not exist, then Eclipse is using the a JRE on the current system's PATH
Change/add the -vm entry to point to a new existing JRE.
Please check your environment settings. Your JAVA_HOME should point to Java Folder and Path should have JAVA_HOME/bin;
I have extracted Eclipse on my C partition. I got windows 7 64 bits. Eclipse is 64 bits. But JDK is 32 bit. Once I run eclipse the pop menu is saying it can't find JDK or JRE on some sort of path. Once I run Eclipse from USB drive it works fine. What is the problem? Should I specify envorinmont variables, set classpath or something? What exactly should I do?
Best regards
Why don't you get the 64bit JDK?
Did you download any java jdk on your pc? To check, open a command prompt and launch the command java -version then javac -version If one of them fails, you need to download java jdk from oracle's website
1. If you are using windows then i will recommend you to download Windows x86 jdk-7u5-windows-i586.exe.
2. Install it... in C:\Program Files\Java\
3. Include this in your System PATH C:\Program Files\Java\jdk1.7.0_05\bin .
3. Then type java -version in your command prompt, and if you get the version of your JDK then, you have properly installed the java, and your path is properly configured.
4. Extract your Eclipse folder from the Eclipse.rar downloaded from Eclipse site.
5. You can place this Extracted Eclipse folder anywhere in the disk, but i recommend you to store it in c: drive as this C:\Program Files\eclipse
6. Now i think it should work.............
In a command prompt, a java -version should show the details of the installed JVM.
For example, a jdk7 32-bit version would show this:
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) Client VM (build 23.1-b03, mixed mode, sharing)
A jdk7 64-bit version would show this:
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)
However, the standard JDK installation copies the java.exe and javaw.exe on the c:\Windows\System32 folder, which could be the ones that Eclipse looks for. This could get really messy if you've tried to re-install different JDK versions and you loose track of the last one you installed (or like me, if you install different versions for backwards support on some legacy projects).
To be 100% sure of the JVM used by your Eclipse, just modify the eclipse.ini file located in your eclipse/ folder so it points to the exact JVM you want. For example, add these lines if you want to use your jdk7 64-bit (check if the same folder applies):
-vm
C:\Program Files\Java\jdk1.7.0_05\bin\javaw.exe
Start Eclipse, and it should work fine.
Go to this site fore more info on the eclipse.ini configuration.
this tutorial is the only thing that worked for me with Win 64 bit.
Summary:
install
32 bit eclipse
32 bit JDK (NOT JRE)
32 bit Android SDK
Add Java to your PATH environmental variable
open eclipse.ini and add a line pointing to the JDK
I uninstalled all versions of Java from my system first.
