Dawn of War Codex

Hi, sorry for this stupid post but i'm a total newbie and I can't make heads or tails of these files.

Which games do you need preinstalled before adding this mod, and do you need to do anything besides the installwizard to get it working?

beta 10 and then beta 11. Beta 11 is just a patch.

You need ''Warhammer 40,000: Dawn of War II – Retribution''
Then follow the instruction given on the download page which atm are:

"Install order for latest version is: beta 10, then beta 11"

thank you for the help!
