That was it, again, thanks Paul. Tested with the nuke (copy every dll from maya to the compiled program's directory). http://msdn.microsoft.com/en-us/library/7d83bc18(v=vs.71).aspx - dll search order in windows.
Seems to me that the simplest method is the last bullet - The directories listed in the PATH environment variable. The PATH environment variable is not the same as doing sys.path.append(path)? The C:\Program Files\Autodesk\Maya2012\bin is already appended to sys.path.... I will get to this later this afternoon, but if anyone have experience with DLL path resolution and particularly the windows PATH environment variable, I would love to hear about it. Is there a way to set that temporarily for the process through Python?
