help ican t add mods

Because every version of Mass Upgrade (MassUpgrade) depends on Satisfactory (FactoryGame) ">=368883" and Satisfactory CL211839 is installed, Mass Upgrade (MassUpgrade) is forbidden. So, because installing Mass Upgrade (MassUpgrade) ">=0.0.0", version solving failed.
Solution
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.
