Thx for the info. I'm on the road right now and can't use my PC until next Saturday, but Im 99.9% sure that it's a 64 Bit OSYou can check using CFF explorer, I believe manual contains video link someone made how to use it. I'll probably add a check and print message to CC log some day.
BTW, 4Gb patch does nothing on 32bit OS, so keep that in mind.
