Error loading DLL in python, not a valid win32 application [duplicate]

by

As the comments suggest, it could be an architecture problem.

If you’re using a 32bit DLL with 64bit Python, or vice-versa, then you’ll probably get errors.

Since I’ve had your error before, I recommend trying to load your DLL with 32bit Python.

One way to test if a *.dll-file is 32bit or 64bit, is to use dumpbin.exe, e.g.

dumpbin /headers dsusb.dll

...

FILE HEADER VALUES
             14C machine (x86)
...

machine (x86) means 32bit, machine (x64) means 64bit.
