Cant install Satisfactory mod loader

I think this is caused by trying to play an older version, I'm now on 1.0. I've tried: -Checking game file integrity with steam -Uninstalling and reinstalling

Make sure you updated the game before launching SMM. If your game is up to date, you have both U8 and 1.0 installed in the same folder at once, and SMM is detecting the U8 version. To fix this, uninstall the game, delete the game install dir if it still exists (this is NOT the AppData folder, but the location where you installed the game), then reinstall the game, and reopen SMM. If reinstalling the game takes too long for you, a quicker fix is to delete the <game install dir>\Engine\Binaries\Win64\FactoryGame-Win64-Shipping.version file, though this is not meant to be a permanent solution, as having the game installed twice in the same directory can cause issues later.

Did you delete the directory as instructed? Uninstalling through steam won't remove all the old files
