Or...
Well then... You need to do this manually...
Go to your BFME 2 game, copy game2.dat, put it in the rc mod install directory
Then in rc mod directory, open the Support folder, in that folder open the:
The Battle for Middle-earth II - RC Mod_code.exe
and enter your BFME II serial
then the game should work
(I am assuming that another small program i made that does this for you... failed to do it, just like the other application )
