The main reason the launcher will not run on some systems, not all, is because your security feautures in Windows 8 and Windows 10 may require Administrative rights.
To run the launcher as Admin, do the following:
- Right clcik on the SWG Resurrection Icon. Select, run as Administrator
Thats it! If it continues to not install, re-install the launcher.
Remember: the launcher is only supported on Windows 7 and up, and you need to get the latest .NET Framework from:
