Answer 1

Did you verify that PyQt4 is for 32 or 64 bits?, I had the same problem I was using python 2.7.13 32 bit in Windows 10 and PyQt4 4.11 64 Bit, and changed PyQt4 for a 32 bit and it work immediately.

Answer 2

I had installed PyQt4 from a .whl file (from the unofficial windows binaries) and got the same error.

I did what the answers suggested: checked that I installed the correct version, put my PyQt4 directory in the PATH environment variable and had QtCore4.dll and QtGui4.dll, however none of these worked.

The answer was to try and open the designer.exe program: it also had an error, but this time specified which DLL file was missing (it said msvcp140.dll is missing from your computer)

I then downloaded it off dll-files.com and put it in the PyQt4 folder (C:\Python35\Lib\site-packages\PyQt4) and it worked.

I hope this helps !

Are you sure you installed Python x64 ? By default, the Python website makes you download the x32 version, you need to go to this page to download the x64 version and then it will work. I had the same issue and it was fixed this way. https://www.python.org/downloads/windows/

Hope that will help someone. Cheers, Chris
