Stuff: First try right clicking the game shortcut, click Properties, click the Compatibility tab and check "Run this program as an administrator".
If that doesn't help I have had good luck using the following install procedure on Win 7 and Vista
1 - Make a system restore point (optional). Create a directory C:\Games if it does not exist. Turn UAC to None before installing even if you are installing outside of Program Files (turn back on after installing.)
(If there is a previous install of the game, backup saves from previous games if they exist. Do an uninstall of the game and delete any directories / files for the game from previous installs if they still exist after an uninstall.)
2 -
Optional for me, disconnect from the internet. Disable or shutdown Antivirus and firewall, the firewall especially can block disk / registry writes. Remember to enable both after the install. I disable them based on previous interference with game installs, if none, I will leave them running (must have internet on some installs).
3 - Install in a directory outside of Program Files / Program Files (x64). I usually use C:\Games as my game directory and create it prior to an install if it does not already exist.
Install by right clicking the setup.exe and click "Run as an administrator" from the resulting dialog. On the first dialog of the GOG Installer, click the Options button in the lower left corner to point the install to the Games directory.
4 - After the install, right click the game shortcut, click Properties, click the Compatibility tab and check "Run this program as an administrator". On the same tab uncheck "Run this program in compatibility mode for", it seems on Win 7 some games run better without any compatibility mode enabled at all. I always start out with none and work my way from newest OS to oldest till I find the mode that works best . . . if I use any mode at all.
This should give a good install which leaves tweaking the game options and config files and video card setting as the only steps remaining.
Make sure you are running the latest video drivers.
Nvidia ATI Thanks, that worked for me. I guess i'm need to get some sleep.
