One known bug which has reared its ugly head as a result of MS not testing FSX on Windows 7, is that the current version of the Windows7 UIAutomationCore.dll is not fully compatible with FSX. The symptoms are a screen ‘freezing” with the sound continuing. It is the result of too many menu or mouse clicks. This is “fixable” by downloading the one from Download
, unzip it and placing in the root folder of FSX.
The Windows 7 version is 6.1.7600.16385, and is resident in the Widows\System32 & SysWOW64 folders. The version needed is 6.0.5840.16386, and is for Vista. It must be simply placed into the
FSX_Root folder and not be registered, as this will change the operating system.
