Installed latest drivers as admin, and turned AV off, no luck. However now I'm not getting the error message anymore I'm just getting "Program encountered a fatal error" a few seconds after running FSX. Wasn't sure what UAC was I'm afraid? Absolute nightmare lol, being a simmer is such a pain sometimes. Just thinking on anything that might help; if I recall when I was shutting down last night windows installed a critical update. I'm also using a fairly old graphics card in the system whilst I wait for a new one to arrive, it's a 5 year old Nvidia 8600GT 256mb. Could be wrong but if windows installed Directx 11 whilst shutting down and this card isn't Dx11 compatible, could it be that? Martyn

Sorry to re-visit an old thread guys but I too am having the same issue. Brand new homebuild PC, windows 7 64 bit and have had it up and running for 3 days now. FSX SP1 + 2 installed on Sunday and have been working fine up until today... Nothing new installed since Sunday. Nothing changed at all. Was even using FSX last night. However on booting up this evening and trying to start FSX I get the error as mentioned by the OP. Have tried deleting CFG, tried rolling back to a system restore point on Monday morning and also re-installed FSX but still getting the error. Any ideas? Thanks Martyn
