Enthought Canopy Lock Error

Question

I have been using Enthought Canopy for quite a while now with the academic license. Till yesterday it was working fine. But now when I try to open it, it is showing

 LockError: Lock could not be acquired

Here is a complete summary of the bug report generated by Canopy:

Subject: Failed to setup your environment

I am using the 64-bit version of Canopy on Windows 7.

How can I get Canopy to work again?

Log out of Windows, log back in again, then delete any of the following files (if they exist) from C:\Users\Dipto\Appdata\Roaming\Enthought\Canopy\:

proc_manager.lock
process.lck
running_procs.pkl

Then restart Canopy.

Then I suggest that you update to 1.1.1, which usually handles this automatically (though on occasion it may still be necessary to log out / log in before Windows itself will release a locked file.)
