I had Maya and a plugin I use working fine, until I think what happened was I was configuring python for use with my computer in general, from the command prompt. So I added a PYTHONPATH environment variable and such. Then when I tried to use Maya again, I got a couple error messages including something like: Code: DLL load failed: %1 is not a valid Win32 application I did a bit of research and remembered that it might be because I had a 32-bit version of python installed, when I have a 64-bit OS and maya install. So I installed a 64-bit version of python (2.7). Then I can't remember the actual sequence, but I was still having issues, so I followed this guide: https://acaciaecho.wordpress.com/2011...on-inside-maya to point Maya to the python install? Now I get an actual error popup when I open Maya: Code: Microsoft Visual C++ Runtime Library: Runtime Error! Program: blahblah\maya.exe R6034 An application has made an attempt to load the C runtime library incorrectly. And this: Code: Error: line 1: ImportError: file C:\Python27\lib\site-packages\maya\app\general\CommandPort.py line 15: DLL load failed: A dynamic link library (DLL) initialization routine failed. And I don't really know what's what anymore.
