thanks for your reply, yes I am very satiesfied with my PC, took some time to get the Money for it, but as I thought it should last for many years now, and I will still hold me to FSX (because of many airplanes and sceneries and other stuff, so I will not go over to Prepare 3D. (to much Work

)
As for your suggestion I have already the line in FSX CFG file and the dll file is already in my FSX directory, it was from 2009, but to be sure I found one and downloaded it and installed that instead, what do You mean by "it has to be specifically from the old Vista OS" ?
to OldAirmail,
it seems like nearly the same I have done, Windows7 and FSX on my SSD drive, and other stuff (included pagefile) on the "big" 1TB harddrive

Hi Snoopy51
In the beginning I used to have lots of problems with FSX, infamously known as OOM (Out Of Memory).
Apparently the file "UIAutomation.dll" that ships with Windows 7 is not compatible with FSX, so the last "known" dll that works with FSX is the one that shipped with the defunct Windows Vista.
It is this "Vista" file that you need.
There are two advocates of "how to do it":
Some people say:
Go to C:\Windows\SysWOW64, cut and remove the file from here and save it somewhere else, even in "my documents", and replace with the new Vista file.
(You may need to take ownership of your files - Google will tell you how.)
Other people say:
Leave the SysWOW64 as it is - just copy the new Vista file straight into the FSX root directory. This is what I have done and it works for me.
(Because FSX finds the file here first, and then ignores the WOW one. - apparently)
Either way, from what I read, the UIAutomation.dll is the windows communication with some of the hardware inputs, mainly the mouse.
Just google UIAutomation for FSX to fine the correct file.Now I am not saying that this is the solution to your problem..all I know it immediately worked for me and I can fly for hours at an end - no more OOMs for me.
Hope this helps you. It worked for me, but it may well be something other..
