BattlEye service implementation in ARMA 3 - DEVELOPMENT BRANCH Posted May 8, 2015 · Edited May 8, 2015 by Prodavec mmand prompt by using "Run as administrator" ? Or if you're using a batch file, right-click and run as administrator? You might have tried that already but I figured it's worth asking. My windows profile has administrative rights, it is inside Administrators group. And yes I just tried to Run As Admin option (Secondary Login service needed) just in case. The other thing I would try (and this is probably way out on a limb) but try turning off "DEP" or data execution prevention on arma3battleye.exe ? If you don't know how, there's plenty of walkthroughs on google.. DEP is completely turned off for all programs on my PC do a verify cache on arma 3 in steam I do it after each arma 3 update. So yes - I have done local cache checking. Maybe the last update messed up your paths or something? Check the keys under this one (this is on my 64 bit system) Probably. HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Bohemia Interactive\Arma 3 Default (REG_SZ): (value not set) data (REG_SZ): %MAIN% MAIN (REG_SZ): F:\Games\Steam\steamapps\common\Arma 3 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Bohemia Interactive\Arma 3\Expansions Default (REG_SZ): (value not set) HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Bohemia Interactive\Arma 3\Expansions\Arma 3 Default (REG_SZ): (value not set) MODDIR (REG_SZ): A3 path (REG_SZ): SOFTWARE\Bohemia Interactive\Arma 3 "C:\Program Files (x86)\Steam\steam.exe" "%1" I didn't find anything related to that string in windows registry. I have found this: HKEY_CLASSES_ROOT\steam\Shell\Open\Command Default (REG_SZ): "F:\Games\Steam\steam.exe" "%1" My Steam had been installed here F:\Games\Steam few years ago and steam.exe is inside that directory. I guess I have to wait some patch/update for BE with some diag / log information (at least error code) stored into Windows Event system and/or .log/.rpt file. Thanks for helping. From now I'm going to play another games.
