I downloaded the single file, the over 1gb one, into a seperate folder, copied it over my RTW, ran the game, found i could only do custom battles, came back here, found the fix, put the fix into my RTW folder, however when i run the game now i can still only play custom battles. I didn't use the launcer.exe, i extracted all the files manually, I have RTW gold edition from steam.
Cheers very much
