Enthought Canopy GUI won't open - enthought

Question

I've downloaded Enthought Canopy Express onto my 64-bit Windows 10 laptop, but when I try to open the Canopy program it won't open.
If I try to open it from the desktop shortcut or go into the program files and try to open it directly from the .exe file, all it will do is show the splash page, which then disappears after showing for a few seconds, and then nothing happens. Also after the splash page is gone, task manager shows that Canopy isn't running.
The PyLab application will open and works fine, but I need the actual Enthought Canopy application to work for a class I'm taking.
When I installed it for the very first time, it did open and I was able to use the Enthought Canopy application, but ever since I closed out of it since then it hasn't worked.
When I go into the program files to try and open it from the .exe file, for the file Canopy.exe it will open the splash page and then close, and for Canopy_cli.exe it will open a command prompt looking window, then the splash page, and then both close. The file _python.exe will open and work, and the file _pythonw.exe does nothing.
(These files are at C:\Users\charizard\AppData\Local\Enthought\Canopy\App if that makes any difference.)
I've uninstalled and restarted and reinstalled several times, and I've tried the "Full Reset" suggested in this article. My user name is just "charizard" and my computer name is "messier42", so the problem isn't that it's a non-ASCII user name.
I have also tried the test to see if it's a problem with the PYTHONPATH or PYTHONHOME environment variables like it suggests in this article, but it didn't start Canopy.
This is what I got from the command prompt when I tested that:
