Solution for Crash of FSX

[Joeflyer]

Emad, aiplayer.dll is usually the result of addon traffic, something fouled up with scenery or possibly an addon aircraft. FsP won't trigger this sort of error or crash. Many times people have to change the graphics card driver to get better results...especially if you are using Windows 10 and a Nvidia card. Sometimes using the latest driver is not the best one to use. I can't tell you how many people have had to do this to get everything working properly lately. It's been a number of them. Possibly it may help in your case.
