Ok; first this is a shame that BI didn't sorted this out before the release of the product. People shouldn't have to go into their registry to make modifications in 2010, only 2% of the PC users knows how to do that. How do you expect people to play your product if its not working properly ? Seriously wtf..
Now, I have steam OA installed only and want to install my Dvd version of Arma 2 to merge them. Also i don't want to read 70 forum pages of support regarding this issue just a simple answer on how to do it would be appreciated.
Thanks.
