Maybe this thread

This EULA doesn't apply to you, but to the Python developers, which are  
the actual Visual Studio users and have to comply with its license terms.
You're just repackaging Python, your program, and other required  
In any case, I don't think MS cares; after all, you're promoting their OS  
and making life easier for Windows users.
