PROS Win 7 Install

I tried installing PROS over a year ago on my Win 7 machine and never really got it to work. I am about to try it again on my school computer so one of the teams can start testing out that environment.
Can anyone give me any pointers to make sure I get it right? Like is there anything I need to install before I do the PROS files, or certain things to check or not check on the install?
Thanks

I see Atom on my desktop now so it must have installed much better than the last time I tried over a year ago.
