Unfortunately I'm unable to play single player OA after having installed DayZ.
I have tried:
1.Launching only the arma2oa.exe.
2.Launching only the shortcut:
Target: "C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\Expansion\beta\arma2oa.exe" -beta=Expansion\beta;Expansion\beta\Expansion -nosplash
Start In: "c:\program files (x86)\steam\steamapps\common\arma 2 operation arrowhead"
3. Rename @DayZ folder
4. Delete @DayZ folder
5. Disabling DayZ expansion from inside the game.
I believe a recent beta patch disabled the single player option - regardless of anything!
This is tragic to me because I can't play OA or CO. In other news, my Arma 2 red harvest campaign is stalled because when the heli transport becomes available once more after use, the game hangs entirely - so I thought to try OA or CO, but no luck there.
Any assistance would be greatly appreciated.
I have today's most recent beta patch installed: 96061.
