I just registered to give a follow up about the erros with the Gamesload download.
First: Gamesload isn't any suspicious seller, it is a plattform of the biggest german communication provider, Telekom.
So, please do not think there's is some illegal action like keys over Ebay etc.
I purchased it yesterday, downloaded the package:
ARMA 2: Black Edition Download v1.11
ARMA 2: Operation Arrowhead Download v1.62
here is the link (not able to link) to the Gamesload package:
world wide web gamesload point de/arma-2-combined-operations/?xtmc=arma2&xtcr=2
First I installed Arma2, running then ArmA2 OA and got the error "no entry ...shadow", bla bla
I searched several hours about that, unfortunately all run into that "run Steam as administrator" answer.
(Obvisously I do not have Steam installed here)
Now I found antipr0duct's description and it solved my issue partially:
It doesn't matter in which order you install that. However I have - as adviced - installed ArmA OA first (running), then ArmA in a different location (have not started it): but got the error again after starting ArmA OA again.
I tried there several combinations.
In the end I downloaded the Betapatch, currently 96751
Copying over any exe's also do not work here, but I can run ArmA OA now with the Beta Link.
However the menue is messsed.
I'm happy now, that I'm at this point, but have not started a game now. Will try.
And I haven't installed/started the DaysZ Mod.
Will report if it works.
If anybody has a solution for this Gamesload issue, please tell us!
