I have no means of running C# programs at present and can't claim much
expertise in any case. A guess is that a "valid Win32 application"
means an '.exe' file, not a '.py' file.
You are assuming that a Process object is as smart as the command
interpreter ('cmd.exe') and will know to use 'python.exe' for a file
with a 'py' extension?
What happens if you use 'python.exe' (or 'cmd.exe') as your file and
the script name as argument as in the code I posted?
