PyPRP2 + Blender 2.61 = possible?

Hi all! I've been muddling along modelling my first age and I would like to experience it from an avatar point of view, as well as adding some fo the necessary Plasma stuff... like floors for avvie to stand on hah.
I'm using Blender 2.61, and I have already downloaded the PyPRP zip and unzipped it, and i /think/ i have put it in the right place... however, I'm not entirely sure if it's in the right place because I have a slightly different file path than what has been suggested for other installations. I'm in Windows 7 (64-bit) and I'm /fairly certain/ i have the 32-bit install of Blender. Anyway, the PyPRP selection does not appear in the Addons tab in User Preferences.
I have the PyPRP folder and the bin folder in the following location: C:\ProgramFiles (x86)\Blender Foundation\Blender\2.61\scripts\addons. In other threads it was said that the two folders needed to go into a scripts folder in users\myname\appdata\roaming\ etcetc, but i don't have one there... the only scripts folder i can find is the one found via the Program Files route.
Also, I don't know how to determine which Blender I have, whether its 64 bit or 32 bit... i can't really remember from when i downloaded and installed. Maybe that's all it is, that i have the wrong version, but i don't know how to find out if i DO have the wrong version.
Thanks for any and all help folks!!
Edit: AND i don't even know if these two things are compatible. If anyone knows THAT answer, that would help too
