chaossound 101 Posted November 1, 2014 So i've been having this issue since Igot a second account, my primary account can play no issue but then when I want to switch to my other account I get a decryption error for PMC, both accounts own Arma 2 and all the DLC Share this post Link to post Share on other sites
Steak and Potatoes 13480 Posted November 2, 2014 Can you post the exact error? Share this post Link to post Share on other sites
chaossound 101 Posted November 2, 2014 Failed to load file "pmc/addons/air_pmc.pbo" - decryption of headers failed. Right now i've got it setup so my second account uses a second install without PMC or BAF installed. Share this post Link to post Share on other sites

You can try running the set up utility however I would try just running as administrator first to see the response. Share this post Link to post Share on other sites

It turns out there is a bug with steam where only the account that installed PMC or BAF can use those. So I have two installs of Arma 2 now =\ one with the DLC and one without. which is a pain in the ass :(. Share this post Link to post Share on other sites
Jerry Kann 2 Posted April 25, 2015 You don't need to have two installs to run two Dayz accounts on the same computer. Here is a workaround for the decryption of headers failed error that only takes a few minutes when switching accounts. http://forums.bistudio.com/showthread.php?173386-ARMA-2-Complete-Failure-to-Load-File-Decryption-of-Headers-Failed-Windows-8-1 Share this post Link to post Share on other sites
