Hello,

could you please try to run Arma as admin (you can find the file in the arma 3 root folder). Thank you.

Doesn't work. Get the same error message. Could it be that this problem is caused by the fact that I just copied Steam folder from one computer to another? DayZ is working fine on both computers though.

It might be.

Could you please verify your game files through Steam?

Thank you.

I did it first thing - it said everything is fine. Also I asked my friend to download Steam folder from my computer and we tried to start Arma and DayZ and result was the same - DayZ works, Arma doesn't. I've download his Steam folder where he have Witcher, Team Fortress, Dark Souls and Dota 2 - every single game worked just fine. I checked this - last time I tried to copy Steam folder and play Arma on another computer it was v 1.04 and it worked, maybe it'll help?

Could you please upload your rpt file?
You can find it here:
C:\Users\<Name>\AppData\Local\Arma 3\

Thank you.

I would've do it in the first place but unfortunately there is no such thing because game does not start. There is no Arma 3 directory niether in My documents nor in AppData\Local. I even tried to copy these folders to troubled computer from the working one - no good.

Well, this is rather unfortunate. Could you please assure that you have all your drivers installed and up to date and upload your DxDiag?

Thank you.

Done.

I finally got my notebook from work, took another one from my friend and asked another friend to download my steam folder. On each of these three computers result was the same - Arma 3 didn't start with aforementioned error message. So it's official now - there is nothing wrong with my computer, but there is definitely something wrong with the game itself. Please do something with it, I cannot afford to download the full game every time I reinstall windows.

Hello,

we are sorry for invonceniences. However, there is nothing that we can help with with no data to examine.

Do I understand right that you do not actually download the game from Steam but use copying older folder instead?

Yes, I've downloaded it once and I'm just copying it now. But please ignore everything I said before and this issue overall - I finally nailed it =). And I'm gonna share my great wisdom with you, he-he =)). As it turned out Arma 3 is the only game I know that needs a use of a Steam Backup function in order to work properly. I should've done that in the very beginning, but as I said earlier, the way with just copying steam folder worked fine before. So thank you very much for your efforts and excuse me for wasting your time.

UPD: I cannot find where to close the issue (I really don't know if I can do it actually =) )

Glad you made it run. Enjoy your time on battlefields.
