To fix the Supreme Commander crashes I tried uninstalling and reinstalling the graphics driver, sound driver, Ethernet driver, Supreme Commander and FAF Client The last two seemed to help a bit but it steadily went back to more and more crashes. I mostly just did replays to avoid disrupting other peoples' games. I disabled surround sound and sound enhancement long ago so it was not that. In the end I fixed it by :- Uninstall Supreme Commander Manually delete folder C:\Users\win-account-name\Documents\My Games\Gas Powered Games Reinstall Supreme Commander When I previously uninstalled Supreme Commander I assumed it removed all the old content but with hindsight I don't think it did. I think a manual deletion of the Gas Powered Games folder was needed to get a clean reinstall. When uninstalling and reinstalling Supreme Commander and the FAF Client I suggest selecting the options that will uninstall the most things. Don't try to retain settings or preferences. A reliable reinstall is more important than retaining old settings that can be re-entered manually. After each uninstall check for any left behind contents and manually delete them before the reinstall. For Supreme Commander check folders :- C:\Program Files (x86)\THQ\Gas Powered Games\Supreme Commander - Forged Alliance C:\Users\win-account-name\AppData\Local\Gas Powered Games\Supreme Commander Forged Alliance C:\Users\win-account-name\Documents\My Games\Gas Powered Games\Supreme Commander Forged Alliance For FAF Client check folders :- C:\Program Files\FAF Client C:\ProgramData\FAForever C:\Users\win-account-name\AppData\Roaming\Forged Alliance Forever Note AppData and ProgramData are normally hidden so they need to be made visible to check them.

I uninstalled FAF using Windows>Control Panel>Programs>Programs and Features I manually deleted folder C:/Program Files/FAF Client I re-installed FAF from faf_windows-x64_2023_12_1.exe FAF then worked fine. Thank you for your help.

Not sure. Maybe in the tech support forum.

The first game is with BlackOps, which is known to have problems at the moment.

Looks like the underlying problem was caused by Norton Antivirus Data Protector. I deleted the old 'C:\Program Files\Downlord's FAF Client' folder and down loaded the latest FAF client installer from https://www.faforever.com/ When I tried to run this I got a "Data Protector blocked a suspicious action by faf_windows-x64_2022_4_0(1).exe" message. I managed to get Norton to exclude this process and then everything seemed to run okay. [image: 1651252965315-2022-04-29-1-resized.png]
