Windows - Canopy 1.1 can fail to restart

(updated December 7, 2013 with new step 2 -- McAfee)

On Windows, Canopy 1.1.0 or 1.1.1 will sometimes fail to restart if the previous shutdown is not complete. This incomplete shutdown could be a result of errors in Canopy or in Windows or by the user, but Canopy should be able to handle them anyway. Our apologies for the trouble -- Canopy 1.2, due at the beginning of December, will correctly recover and restart, in all cases of which we are aware.

There is no need to uninstall and re-install. 

Instead, try each of the following steps, in this order, until Canopy starts. Steps 1, 2, or 3 will usually be sufficient.

 

1) Log out of Windows and back on, then try to restart Canopy.

 

2) If you are using McAfee Anti-Virus, disable it (thus automatically re-enabling the standard Windows Anti-Virus). With some update versions of McAfee, Canopy is prevented from restarting.

 

3) Delete the Canopy configuration directory, thus:

From the Windows Start Menu, open a Command Prompt window, and type the following command:

rmdir  "%APPDATA%\Enthought"  /s

Then try to restart Canopy.

 

4) (Usually will not be necessary). Delete the Canopy System virtual environment directory, thus:

From the Windows Start Menu, open a Command Prompt window, and type the following command, depending on your Windows version and Canopy 32/64-bit version.

Windows Vista, 7, or 8 (Canopy 32-bit):

rmdir  "%LOCALAPPDATA%\Enthought\Canopy32\System"  /s

Windows Vista, 7, or 8 (Canopy 64-bit):

rmdir  "%LOCALAPPDATA%\Enthought\Canopy\System"  /s

Windows XP (Canopy 32-bit):

rmdir  "%USERPROFILE%\Local Settings\Application Data\Enthought\Canopy32\System"  /s

Windows XP (Canopy 64-bit):

rmdir  "%USERPROFILE%\Local Settings\Application Data\Enthought\Canopy\System"  /s

 Then try to restart Canopy.

 

5) Email canopy.feedback@enthought.com, summarizing what you tried and what happened.
