I am running vanilla 4.09, HSFX, Ultr@Pack and a SAS mod version under Win 7 Pro 64 bit. I have had no problems nor have had the need to emasculate any eye candy.
Through a process of trial and error, the only "special" measures I took were:
- Install the games in their own Games directory (eg: C:\Games\Sturmovik_v409_UPv2_01\IL2-Sturmovik1946) not the default Programs directory suggested by the installation program;
- Right click on il2fb.exe ( or whatever you use as the executable - mine is modded to access the 4GB of RAM available under 64bit systems) go to the Compatibility tab > Change settings for all users and tick "Run this program as an administrator" > Apply > OK;
- Go through the same compatibility process for the shortcut to il2fb.exe (or whatever) you use to start the game;
- Go through the same compatibility process for the .exe files and shortcuts of any other programs you are using with the game - eg: Track IR, HOTAS programs, graphic driver/mod programs like NVIDIA control panel, etc.;
Cheers,
