Loading screen 97 [map name].ng5

[Igolans]

Hello.
I've recently downloaded DCS World from Steam and soon after it, the game starts crashing on loading screen 97 Caucasus.ng5 . Straight after the download, it got no problems and I could easily fly the Mustang. But when I wanted to open it for the second time, the game crashed on the previously mentioned loading screen. I searched up a topic when one guy had the same issue and I did all of the steps, but none of them worked. Then I thought that maybe it's an issue with the map itself so I bought Syria map + F/A-18. When I tried to run it on the freshly bought map it also stuck on 97 Syria.ng5 . I don't know what to do, my computer meet the steam recommended requirements but it does not work. I will attach my DCS log if it could help. Thank you in advance for helping me out.

I dropped your log file into the DCS log analyzer which reported at least one item which aligns with your log file.

The crash appears to be it attempting to write (unpack) files.

You'll see there that it doesn't have permissions to write to that file path. Can you delete the "C:\Users\igort\AppData\Local\Temp\DCS" directory and try again.

Have you ever attempted to run DCS as an administrator? Don't do this, but just wondering if file permissions error.

I tried changing the windows page file from 16GB to 64GB and it still don't work. I also tried changing the graphic to low and the only change is that it is now stuck on the loading screen 96 Syria.ng5 instead of 97 Syria.ng5 .

Thank you very much. I deleted the \Temp\DCS and now it works. Answering your question - I have never run DCS as an administrator.

Where is this folder "\Temp\DCS'' ? And what files did you delete from there ?

Do you have exactly the same problem as this post and log errors? You probably shouldn’t hijack old posts. If you have an issue then raise a new post and attach your logs.

You don’t need to install DCS again. Just remove any mods and run a slow repair of the game.

Problem is solved by reinstalling system from WIN11 to WIN10 . Not the easiest way, but in my case i made such decision
