I have a 64bit Windows 7 machine. Never had issues with EPD.
I repeatedly tried to install both 64bit and /or 32bit Enthought Canopy.
Despite installation being successful neither of them starts.
I looked on Task Manager and the process does not even start.
I have removed every other version of Python I have had and still no ability to launch caonpy
any advice on how to solve this?
Delete the environmental variables called PYTHONPATH and PYTHONHOME
Go to Control Panel\System and Security\System > Advanced Settings > Environmental variables.

Installing Canopy 2.1.9 for Windows 64-bit on Windows 10, and the installer fails immediately after clicking the Install button, with the message "Enthought Canopy (64-bit) Setup Wizard ended prematurely because of an error." Same result using 2.1.8. Same result using the run-as-administrator command line msiexec instructions, same result running the installer as administrator, same result installing for current user or all users.
Enthought support here. Sounds like there's something unusual about your current system status. Most likely would be interference from a 3rd-party anti-virus program, or similar. If temporarily disabling that doesn't help, then please run msiexec /Lv*x canopy-msi.log ... etc..., then zip and send the resulting log, with a link to this SO question, to support#enthought.com. We'll look at it as time permits, though we do not have the bandwidth to help you debug your system setup.
I have been using Enthought Canopy for quite a while now with the academic license. Till today it was working fine, today I got the request to update Canopy. I assume to version 1.7 since that seems to be the latest. After installing and restarting the computer no error message but Canopy does not open anymore. Just nothing happens when I try to open Canopy, Package Manager, Code Editor nevertheless the Canopy cmd seem to be fine.
Now it is getting interesting, I can still start Ipython/Jupyter notebooks via regular win cmd and run python scripts with Canopy. Although the files are no longer marked as to be opened by canopy with the blueish symbol and do not open on click or double click as before.
import sys
print sys.prefix
C:\Users\MYNAME\AppData\Local\Enthought\Canopy32\User
Consequently, I can work and I am hesistant to try fixes since I am afraid to make it even worse. Reinstall is is only okay if I can get back all my installed libraries with ease.
However, I found very convenient to use canopy since I was able to start ipython notebooks directly in the file explorer by double click instead of going through the cmd. Furthermore, the Package Manager is also a quite handy tool, I really would like to have both back working fully.
Thank you for your suggestions:
System:
Windows 8, 64-bit operating system
Installed Version of Canopy:
`Canopy32\\App\\appdata\\canopy-1.6.2.3262.win-x86\\lib`
(consistent in sys path and control panel - program and features)
The Canopy Support Directed me to a working solution:
Note, uninstalling Canopy does not affect your installed package set.
You have two choices:
A) It would be cleanest to start with the up-to-date package set in
Canopy 1.7.
To do that, then after you uninstall Canopy 1.6, but before you
install 1.7, delete directories:
C:\Users\MYNAME\AppData\Local\Enthought\
C:\Users\MYNAME\AppData\Roaming\Enthought\ B) However if you have a
number of non-Enthought packages installed into Canopy, which would be
troublesome to re-install, you could choose to delete the above
directories and their subdirectories, with the exception of this
directory C:\Users\MYNAME\AppData\Local\Enthought\Canopy32\User\
which is where your existing packages are installed.
If you do this, then after restarting you'll be running Canopy 1.7 but
with your pre-existing package set from Canopy 1.6.2.
I chose to deinstall 1.6. and install 1.7.1 and I did not delete the directory with the external libraries.
Just installed Eclipse Mars on Lubuntu 14.
While scrolling up and down in the console or editor - I get a kind of black rectangle covering some text, or the test is kind of twisted visually (lines become non-straight).
Anyone know how to fix this?
Haven't had this in previous versions of Eclipse on the same comp.
Exactly the same thing happened to me installing Eclipse Mars on Lubuntu 14 Toshiba Satellite notebook. I was really looking forward to the day of the Eclipse annual release of Mars and I was disappointed to be so disappointed with 5 minutes on installing.
Anyway, I can confirm that setting environment variable SWT_GTK3=0 by way of export does circumvent the problem. If you open a terminal and type "export SWT_GTK3=0" in the shell, you will also need to start Eclipse via the command line while remaining in the same shell. If you start Eclipse via a desktop launch icon, Eclipse will not see the SWT_GTK3 environment variable and the problem will persist. This is because environment variables in Linux are per-process and an application launched from the desktop is running in a different process to a shell process in a terminal.
So that Eclipse always sees the correct SWT_GTK3 environment variable after starting your machine, best you export SWT_GTK3=0 globally. To do this on Lubuntu, follow these steps:
Open a terminal window
Open the file /etc/profile for editing as sudo (e.g. sudo gedit /etc/profile)
Add the line
export SWT_GTK3=0
at the end of the file.
Save file, quit editor and reboot your machine.
Launch Eclipse Mars and hopefully your scrolling problem is fixed.
This worked for me but, as always, YMMV.
btw. You can check the SWT-GTK3 environment variable was exported after rebooting by opening a terminal window and typing the 'env' command. You should see
SWT_GTK3=0 in the list of environment variables and values that are displayed.
It seems like a new bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=469027
It happens also under Kubuntu. Anyway the workaround, at least for me, is to export the following environment variable:
SWT_GTK3=0
I solved my problem in Ubuntu 15.04 with Eclipse Mars by adding the following code in the start of data in the Exec option in eclipse.desktop (/home/.local/share/applications):
Exec=env UBUNTU_MENUPROXY=0 SWT_GTK3=0 /usr/lib/jvm/...
In that way you leave intact your OS preferences and act only on Eclipse starting script.
I was previously running Enthought EPD 7.3.2, but switched over to Canopy (academic license). I completely uninstalled EPD before running the Canopy install.
After installing Canopy, I have a shortcut to IDLE in the Canopy start menu folder, but I can't get it to launch (I click it and nothing happens). Tried uninstalling and reinstalling Canopy, but am having the same issue.
Running the 64-bit version of Canopy on Win7, 64bit.
I had a similar problem and found a very simple solution. Try it out and see if it works in your situation too. There is a directory for the Canopy installation:
C:\Users\\AppData\Local\Enthought\Canopy\App\appdata\canopy-1.7.4.3348.win-x86_64\Lib\idlelib
Find “idle.ico” file there, copy and paste it into “Icons” subdirectory.
This fixed the problem!
Canopy 1.0 and 1.0.1 versions have problems with tcl and TKinter, and IDLE doesn't work. This should be fixed in an update, which is just round the corner.
As an afterthought, is there a specific reason you wish to use IDLE? Canopy's editor comes integrated with an IPython console (along with many other goodies), which gives a much better user experience while programming, IMO. (Disclaimer: I work for Enthought)
I just got this MSI wind netbook and tried to run eclipse on it. I installed JDK6 on the netbook already. Whenever I open eclipse there is nothing show up on the screen except a "warning sound" that alerts. What is the problem here?
ps.I just started learning java.
Most likely the Eclipse starter program can't find where you installed Java. Since Eclipse is a Java program, it needs a JRE installed (comes with the JDK typically) to run. Assuming you're running Windows on your MSI Wind, check to make sure the java executable is on your path in your computer environment settings (windows key + printscreen button, or windows key + pause button are the shortcuts to open the computer properties dialog if I remember correctly. Then go to advanced).
You can test if java is on the path by opening a cmd.exe shell window and typing 'java'. If it says it cannot find java, then you need to fix the path.
See this link for additional troubleshooting details: http://www.eclipsezone.com/eclipse/forums/t99010.html
You could try reinstalling the JDK. Perhaps having it on a different disk than the default (D: versus C:) is causing some trouble? It certainly isn't a problem with the hardware, I'm running Eclipse on Windows on an MSI Wind.
Use "Add/Remove programs" in the control panel to remove the java versions you have installed.
Then visit "java.com" and use it to install Java, and verify that it is working. You do not need more than that to use Eclipse.
