Pseudoman: I guess that there are 2 ways to uninstall a game like ROTT:
1) Use the start menu shortcut for the game uninstaller:
Start -> All Programs -> GOG -> Rise of the Triad -> Uninstall
2) Use the Control Panel:
Open Control Panel -> Uninstall a Program -> Rise of the Triad -> Uninstall
See:
Microsoft.com It doesn't tell me which ROTT is which. it just has two files in the uninstaller called "Rise of the Triad" with no mention of whether it is 2013, Dark War, the patches or anything else related to them. the file dates tell me nothing either,
