bond1971@tpg.com.au 92 Posted August 6, 2012 Make sure that you have run both ARMA2 and ARMA2 Operation Arrowhead at least once, this will create a registry entry for the key and also submit it to the hive. On one of the kids machines this actually took about 15 minutes delay until the key was accepted.For now, just run these two games at least once and then try Dayz.

DJE1337 8 Posted August 6, 2012 (edited) wtf? my shit don't work! keeps saying "Bad serial number given in Setup" .... WHY???You need to run steam as an administrator which will allow it to create the registry entry. Edited August 6, 2012 by dje1337 Share this post Link to post Share on other sites
wombraider 20 Posted August 6, 2012 If you're using steam, verify the game cache. Then run Arma 2, then OA then CO and then it should work. Share this post Link to post Share on other sites
safety-matches@hotmail.com 1 Posted August 6, 2012 thanks for the advise but I didn't get arma2 or arma2 OA through steam. I can't run arma2 OA, as soon as I open OA it starts to load then the "Bad serial number given in Setup" tab comes on the screen :/ Share this post Link to post Share on other sites
