I too am at a loss. After running FSX for at least two years it has suddenly crashed. I cant even start it anymore!
I uninstalled all my add-ons (that took me a whole day) then uninstalled FSX, re-booted my system and installed FSX again. After re-booting the system
I started FSX, no problems. Then I installed SP1, re-booted the system and started FSX, again, no problems. SP2 was then installed, re-booted and crash!
Here is my system :
Cougar Tower
i7-2600K @ 3.40Ghz
GeForce GTX560Ti, Driver 320.49 running @ 1920x1080,60
16 GB-RAM
WIN7 Home Premium
6.1.7601, Service Pack 1, build 7601
As soon as I uninstall SP2 again, everything is fine!
I installed the 320.49 driver last night and then installed SP2 and it worked! (Firefox has also crashed at the same time as FSX, but it too was running again after the driver update). When I tried it again this evening, the same thing, crash at start-up (Firefox too!).
I am sure that it all started when the last WIN7-Update was put on, but I could be mistaken (who doesnt blame MS for everything!).
As I said at the start, two years of running without problems, now this!
If there is anyone out there who could help me, you would make my day! (firehawk44 ???)
(Just looked at my Visual c++ version, its 2010 x86, 10.0.40219)
