Few days ago I bought Arma 2 and Arma 2 : Operation Arrowhead.
This is how I installed them :
Downloaded and Installed Arma 2 to C:\Program Files (x86)\Bohemia Interactive\ArmA 2
Ran Arma 2 and started a mission, saved the mission and closed Arma 2.
Downloaded and Installed Arma 2 : Operation Arrowhead at the default setup location : C:\Program Files (x86)\Bohemia Interactive\ArmA 2 (Same file I installed Arma 2 in).
Ran Arma 2 : Operation Arrowhead and this is the error I received. http://prntscr.com/detvq .
I've spent literally about 10 hours browsing forums, asking friends etc to try to fix this, obviously nothing worked so I concluded that I should make a thread about this.
This is what I've tried already to fix this.
-Fully Uninstalled and Re-Installed the game ( Both Arma 2 and Arma 2 : Operation Arrowhead )
-Patch Both games and this is the error I got trying to do so : http://prntscr.com/deu2p
-Tried the program Regfixer.exe.
More Information: I do not have this game on steam. I use Six Launcher in order to launch this game and play DayZ.
This game is located in HKEY_CURRENT_USER\Software\Bohemia Interactive Studio\ArmA 2 according to REGEDIT.exe
Any help or Remote assistance would be grateful.
