.py to exe error "oserror winerror 193"

[michael1789]

My search show that this is a common error when trying pyinstaller.

Error:
oserror winerror 193 1 is not a valid win32 application

Something about conflicting versions of Python... I think. I'm not sure if it my editor "Thonny" that is the problem, or my Python3, or my windows OS.

Is it that my windows is 32 bit, and my python3 is the 64 bit version? or visa versa? I don't really even know what that means so I wanted to check if anyone here doesn't before I start uninstalling and reinstalling stuff (incorrectly).
