I wish I had the good luck charm that both ejoiner and jetsmell have. My experience with FSX and Win 8.1 have been not good at all.
I recently purchased a new computer (July 2014) that runs on Win 8.1 so I can finally fly FSX (both SP1 & SP2 are installed). I am having constant "Fatal Error detected" crashes. I've been reading all the Forums out there and tried all of the "fixes" but so far, no joy.
So, I'm not sure what people are doing to solve these constant crashing problems. I'm just about ready to go back to my ancient Pentium II system with XP so at least I can start flying again, even if it is FS9.

By the way, what does "UAC" stand for? Thanks.
