hi I'm planning on buying a new desktop PC and i'm not quite sure if I should get windows 7 (64bit) as i don't know if it causes any problems with FSX or the 747X addon by PMDG ... does anybody have fsx installed on windows 7 home premium ? and can anyone give me some information on how the 747 behaves on win7 ... has anybody experienced CTDs or else? thanks Danps. i know that there's a similar thread on this subject but i opened another one because i didn't find the answers i hoped for...sorry for that ! :(
