Yes, PP is compatible, but I noticed you can't change the location of your INI file (it's hardwired in the path location box).

Don't know if it was that way on Win7 as I never used it on that OS. I wanted the INI file stored somewhere else (as I had done with my previous installation on an XP system) but no way to work that for now, I guess.
I had a problem getting PP to see all my previous accounts and settings info as well.

I put all the files in place and started the app, yet it refused to read the INI.

I finally made a new blank INI file by starting the app w/o on in the necessary directory, shut PP down, copied my INI file over the blank and then PP finally recognized and used it.

Is that a permissions issue with the old vs. new file? Shouldn't have been, but my method worked so something changed.
Good Luck all.
