PyPrp and Blender on Windows 7 (problem)

I'm having trouble with installing PyPRP in Blender with Windows 7, because in my Windows 7 installation of Blender there is no .blender folder, and Windows 7 is making it impossible for me to create one.
How can I install PyPRP in Windows 7? I can't seem to make it work!
