I downloaded Tiberium Wars via Origin in a game bundle, and I want to make custom maps for it. I used to make maps for RA3 so I understand how it all works, finding the folder in AppData etc, now here is my problem. I made a map, I've put it in the right folder as instructed on several web pages (AppData -> Roaming -> C&C3 -> Maps) but it doesn't appear when I try to test it in game. So I downloaded the map manager, and it gave me the error in the gyazo link below. I don't even know what to do anymore about this, can anyone help me out?

I am having the same issue. I also have the Origin ultimate addition of the game and have installed maps in the same location with no luck and also tried the map manager and I also get the same error message. can anyone help us out?

Might be caused my missing registry entries. I would recommend installing my fixed launchers and run the game at least once before trying the Map Manager again. Or you add the missing registry entries manually.

Fixed launchers can be found here:

Edit:
Ok, this Map Manager doesn't work for me, too. Maybe it's oudated. Custom maps work fine for me anyway.
Could you post the exact path you are putting the maps to?
