Well I read that Horizons was alive again and wanted to log back in after being away for 8 months. I am running Vista Ultimate and had problems getting it to run. However, I got it working by following this simple process:
1. Goto the file \Program Files\Tulga Games\Horizons\HorizonsLauncher.exe
2. Right click on the program and select "Run as administrator"
Thats it. Runs just fine.
