Here's a suggestion I found on avsim.com
Try this only if you have at least 2 GByte of RAM and at your own risk.
First download the explorer from http://www.ntcore.com/exsuite.php
Next make a copy from fsx.exe. Than start "CFF Explorer" and open the orginal fsx.exe file.
Now go to NT Header/File Header and click File Header. Ther you find a button labeld "click here". Click it. And select the mark at "App can handle> 2gb adressest "
Save the modified EXE, overwrite the orginal one (You have youre copy saved?).
If you run Windows Vista 64 or Windows XP 64 youre ready and didnt need to read on. The rest is only for Windows Vista 32 or maybe Windows XP.
Now make Windows Vista (32-Bit) ready to support more than 2 GByte.
Open a command prompt with Administration rights. You find it under "Programs->Accessories->Command prompt" click right and select "run as administrator".
Enter "bcdedit /set IncreaseUserVA 3072" (without quotes) in the command window and press enter.
After that restart windows
For Windows XP there is a similar setting for the boot.ini, but I have no Link to it, should be found be google.
For me it solve the problem
