You have to do a manual installation, that means you have to select the start exe of the game in the folder. Then you have to start the game normally (not via WeMod) and only click on “Start” in the main menu at WeMod and switch back to the game and wait a moment then it should work.
Mods won’t stay turned on even though game is recognized mods won’t work. Please fix!
Update: mods will officially work with the HD Edition
