you downloaded and installed the beta patch successfully? did you check if the beta folder is present in your steam OA\expansion folder? just checked the .cmd from dwarden is different now :uac_PATH_A2 @FOR /F "tokens=2* delims= " %%A IN ('REG QUERY "HKLM\SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2" /v MAIN') DO SET ARMA2PATH=%%B IF ERRORLEVEL 1 GOTO std_PATH_A2 IF ERRORLEVEL 0 GOTO uac_PATH_A2OA :std_PATH_A2 @FOR /F "tokens=2* delims= " %%C IN ('REG QUERY "HKLM\SOFTWARE\Bohemia Interactive Studio\ArmA 2" /v MAIN') DO SET ARMA2PATH=%%D IF ERRORLEVEL 1 GOTO ENDfailA2 IF ERRORLEVEL 0 GOTO uac_PATH_A2OA :uac_PATH_A2OA @FOR /F "tokens=2* delims= " %%E IN ('REG QUERY "HKLM\SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA" /v MAIN') DO SET ARMA2OAPATH=%%F IF ERRORLEVEL 1 GOTO uac_PATH_A2OA IF ERRORLEVEL 0 GOTO RUN :std_PATH_A2OA @FOR /F "tokens=2* delims= " %%G IN ('REG QUERY "HKLM\SOFTWARE\Bohemia Interactive Studio\ArmA 2 OA" /v MAIN') DO SET ARMA2OAPATH=%%H IF ERRORLEVEL 1 GOTO ENDfailA2OA IF ERRORLEVEL 0 GOTO RUN :run "%ARMA2OAPATH%\EXPANSION\BETA\ARMA2OA.exe" "-mod=%ARMA2PATH%;%ARMA2OAPATH%\EXPANSION;ca;%ARMA2OAPATH%\EXPANSION\BETA;EXPANSION\BETA\EXPANSION" "-nosplash" "-exThreads=7" :end @exit :ENDfailA2 @exit :ENDfailA2OA @exit thats mine actually

Updated thread for Steam Arma2 + Steam OA + Beta Patch http://forums.bistudio.com/showthread.php?t=101615 Dwarden could you check please if this stuff is right? :)

mods go into your main OA directory lets say @CBA looks like this :run "%ARMA2OAPATH%\EXPANSION\BETA\ARMA2OA.exe" "-mod=@CBA;%ARMA2PATH%;%ARMA2OAPATH%\EXPANSION;ca;%ARMA2OAPATH%\EXPANSION\BETA;EXPANSION\BETA\EXPANSION" i dont know if there are mods that depend on loading arma2 and OA stuff first, but if thats the case i looks alot worse then it is already :run "%ARMA2OAPATH%\EXPANSION\BETA\ARMA2OA.exe" "-mod=%ARMA2PATH%;%ARMA2OAPATH%\EXPANSION;ca;%ARMA2OAPATH%\EXPANSION\BETA;EXPANSION\BETA\EXPANSION;%ARMA2OAPATH%\@CBA"

:run "%ARMA2OAPATH%\EXPANSION\BETA\ARMA2OA.exe" "-mod=%ARMA2PATH%;%ARMA2OAPATH%\EXPANSION;ca;%ARMA2OAPATH%\EXPANSION\BETA;EXPANSION\BETA\EXPANSION" "-nosplash" "-world=empty" "-cpuCount=4" "-exThreads=7"

It actually works like that http://forums.bistudio.com/showthread.php?t=101615 :) But as animalmother said over there, it doesnt recognize startoptions form steam and stuff thats why i asked :)

Dwarden is there any possibility to make a batchfile that searches for your arma2 install and merges the nessecary files to your OA installation? Or let us browse to arma2 install folder manually inside the expansion menu in the main menu of OA? Would be a nicer solution then this batchfile for users who own arma2 and oa on steam. or give steam a third option to download combined arms as a standalone if you own arma2 and oa on steam. As it is now it causes problems to run beta patches combined with custom mods.
