fyrflygrl Posted September 4, 2023 Share Posted September 4, 2023 I recently had to reinstall Windows 10. Since the install, every time I open ME3Tweaks Mod Manager, I get a popup that says "This operating system is not supported. This application has only been validated for use on on the following operating systems: Windows 10 (not EOL version)". I'm running Windows 10 Professional, version 20H2, OS build 19042.1706. I even tried changing the compatibility to Windows 8 and then Windows 7, with no luck. I've never has this problem before. Any help would be greatly appreciated.

VlKlNGS Posted February 24 Share Posted February 24 (edited) Try another version of windows? I have win 10 enterprise version 10.0.19045 build 19045 and mod manager version 8.2.4 build 133 and it worked fine for the bit that I tried it.
