This can be for a number of reasons. Most common are video drivers and a problem with the redistributables that the game needs installed to run. The instructions below reference the Steam version of Galactic Civilizations II - Ultimate Edition.


Please go to your video card manufacturers website and install the most current drivers.






If the above does not help, navigate to where the game is installed (typical locations below) and run the following files:

32bit: C:\Program Files\Steam\SteamApps\common\Galactic Civilizations II - Ultimate Edition\redist
64bit: C:\Program Files (x86)\Steam\SteamApps\common\Galactic Civilizations II - Ultimate Edition\redist


After, please reboot and try to run the game again.


Corrupt .bin file:

Please press the Windows key and the 'r' key to bring up the run dialog. Paste in the following and hit enter: %ProgramData%\Stardock\GC2UL

The window that comes up will have the sig.bin activation file for the game. Delete it. Run the game again and activate when prompted and see if the issue persists.


Missing \ Corrupt settings:

Delete the 'Prefs.ini' file in: C:\Users\YOURWINDOWSUSERNAME\Documents\My Games\GC2TwilightArnor

Try to run the game again.
