Dawn of War 2 and Chaos Rising

[Codename: Lama]

*****Works on Windows 7 for me*****

If u have problems with launching (pops command line window and closes in an instant)
Something like this helped me:
1. Uninstall all microsoft games for windows live/marketplace (had both so uninstalled both of them).
2. Install gfwl from steam/steamapps/common/Dawn of War 2/Install/gfwlivesetup.exe
(or any other location where you installed the game)
3. Try it.

As I said at the beginning it works for me. Hope that for you too.

Sorry for my English ;)
