cx_Freeze and win32ui - ImportError: DLL load failed

Question

I'm trying to build an exe with cx_Freeze.

It worked before but since I have imported win32ui in my Python program, I get this error when running the created exe file:

I double checked, the following line is the cause:

import win32ui

Importing win32print works fine though.

I'm using Python 2.7 and PyWin32 build 220

Answer 1

I had the same issue as described, the solution was to include the pythonwin folder in the environment path. More specifically the mfc140u.dll is required to ensure that win32ui.pyd imports correctly.
