Python 3.3.4 Cx_Freeze ImportError: DDL load failed: The specified module could not be found

Question

I am attempting to use cx_Freeze to turn a .py file that I wrote in Python 3.3.4. In running the build command, I get the following error.

C:\Python33>c:\python33\python.exe setup.py build
running build
running build_exe

ImportError: DLL load failed: The specified module could not be found.

Have I not installed cx_freeze correctly? Or am I running it all wrong? Help is greatly appreciated. Thanks

Answer 1

Well, I found an answer that works for me.

Turns out there's a bug in cx_Freeze 4.3.4 and downgrading to 4.3.3 solved this problem for me.

Try opening up the util.pyd file with a tool like Dependency Walker in order to check if the error is a result of missing dependencies. I found that it was trying to load msvcr100.dll from the Microsoft Visual C++ 2010 runtime which I did not have installed on my machine. If this is also the source of your error, you can try running the x86 / x64 installer to see if this addresses it (you want to pick the one that matches the architecture of your Python installation not of your OS).
