To further GunsForBucks' OP here, some players have reported they installed their mods in a different folder than the game installation folder. In this case, you will need to go to where you installed those mods and delete them, or use your mod launcher to uninstall them.

Wow... that makes it even harder to make sure they are gone since they are not all in one spot. Mods should not work that way or they could end up breaking multiple games.. that is kind of insane. To say nothing of cheat engine detection issues for games with anti cheat.
