Hello everybody I just installed fs9 onto my vista system. I installed fs9.1 and everything else all updates so on and so forth. Well when I load a plane I get a ctd error with the details saying App Crash. So then I searched the forums and a little tip was to make it run under xp compatability mode. Well this made it worse. The sim did not even make it to the actual flying part and crashed in the loading part. Any help?

I would do a complete re-install. I have Vista Premium and have checked the XP compatibility with no problems. Something is very wrong with your installation. Make sure the set up is going to the proper program files folder.

Actually I fixed it. The source of the problems was active sky and now I run all under xp2 compatability mode. Thanks for your help.

Good job. Often times if that doesn't work, also run as administrator. Vista is very different.
