That was not clear, Personally i did not understand that the command should be put in the mod manager. It was written "Use -o:"c:\OutputPath\" command line parameter to change where files are generated to, default is the game folder. Then install output as a mod.
Do not generate into any game, any mod manager folders or special Windows folder like Program Files x86, Users, Desktop, Documents, Downloads etc." but with no precision where to put the line parmater, i don't know what a line paramater is, so it propably didn't helped, but it could be good to put a precision in the instruction.
