PyQt5 - 64bit - ImportError: DLL load failed: %1 is not a valid Win32 application



  • Hi,
    I had a hard time getting PyQt5 to work on 64bit OS. I kept getting error while importing the modules.
    [code]ImportError: DLL load failed: %1 is not a valid Win32 application.[/code]

    Python & PyQt5, both were 64bit versions. Clean Re-installing them did not fix issue.

    Ultimately i had to remove both & install 32bit versions of Python & PyQt5.

    This is just to help anyone who might encounter the same issue.
