Not that I'm a Windows user, but your example doesn't appear to make any
sense to me.
According to the docs:
args should be a string, or a sequence of program arguments. The
program to execute is normally the first item in the args sequence
string, but can be explicitly set by using the executable argument.
There is no executable argument passed in your example, so the first
argument should point to an executable.
'ftype py=C:\Python25\Python.exe' doesn't seem like an executable to me.
