I had the "error loading game" problem and when i run as an adminstrator it doesn't show my saves anymore. Where are my saves stored and where can I move them to to make them work with a run as admin game?

To be more clear where would the save files be if you didn't run as an administrator? Because the save folder doesn't exist if I go to it through programme files.

Edit: Problem solved. Wasn't sure where it was (some sort of vitural store on windows, forgive the spelling.) but I searched for .sav and it popped up. I dragged in into the save folder and it popped up fine. Hopefully anyone else who has this problem can follow this.

Jagged Alliance has quite a few problems with UAC. So you'll either have to run the executable as administrator, or better yet install to a non-system folder (C:\Games\JA2 for example)
The location of the saved files (incase anyone else has the same problem) is C:\Users\{your username}\AppData\Local\VirtualStore\Program Files (x86)\GoG.com\Jagged Alliance 2\SavedGames
In case you do not have the gog version, but another, it will still be Program Files (x86)\{Install Directory}
