I have a Python app I wrote on Linux and I’m trying to port to Windows. It works perfectly on Linux
I’ve tried half a dozen or so different suggestions to get this to work, to no avail. It keeps failing at the ‘import matplotlib.pyplot as plt’ line. Here’s the info dump. Whatever I did wrong, I promise I will never, ever do it again, Ok? Thanks in advance.

Thanks Dominik! Using that as a breadcrumb I was able to trace that the problem was I needed to install VC++ redistributable (for 2015) from MS in order for matplotlib to work right!
tried in Python 3.8 for Windows 7, 32-bit
C++ 2010 Redistributable
installed

You’re reporting an unrelated problem. " _multiarray_umath.cp38-win32.pyd" from the numpy package is causing a STATUS_ILLEGAL_INSTRUCTION (0xC000001D) exception to be raised. Either the PYD (i.e. DLL by another name) is corrupt or a bug in it caused the instruction pointer to jump to an address that has an instruction that’s illegal to execute in user mode.
