Hey, So I own non-steam Arma 2, OA, and BAF and PMC dlcs and when I used to play them last year they all worked fine. But I just re-installed Arma 2, Operation Arrowhead, and re-downloaded BAF and PMC DLC. The game itself runs fine but when I install either of the DLCs 7-zip extracts the files, reaches 100% and then i get a message saying "access denied". I've download all the patches for Arma 2 (up to 1.62 I think). I've tried running the installers as administrator. I've tried changing the owner of the Arma 2 file and the addons file but that hasn't worked either. I've tried googling and searching forums and haven't come up with any solutions yet. Can someone please help? Many thanks in advance.

Hey Robert, I looked on armaholic yesterday and it said you had updated your HK416 pack for OA, but I didnt get around to downloading it. Now when I look I can't seem to find it anywhere?
