If your copy of Act of War: High Treason won’t launch and you see no error message, try this;
- Go to the installation folder of Act of War: High Treason.
- Look for “9760_install.vdf” file and open it with any text editor (I prefer Notepad++).
- Find “WINXPSP3” (There are more than one).
- Replace them with “WIN8” (Don’t worry, even if you don’t use Windows 8, it will work. It just changes the compatibility mode).
- Save file.
- Launch Act of War: High Treason.
This will fix your problem 🙂
