Yeah I tried every solution, the one deleting repeated lines(Wich I didn't have any!), copying other people fsgame.ltx, creating a bat with the lines start bin\xrengine, etc. The strange thing is if I use the gog launcher of the game, the one with the round icon that says launch stalker... it works but not the one in bin(xrengine) and I dont want to always launch gog galaxy everytime I want to play stalker like if it was steam.

Edit: stalker soc works well, but the same problem occurs with call of pripyat, Stalker-COP.exe and the gog one works well but the same problem with clear sky happens with the bin one, this last one doesn't bother me as stalker cop is the exe I need, to play completely offline and tranquil. But I mention it because maybe there is another solution, that I'm unaware of, like having to exes as if it was stalker cop(one in bin, the other in the game folder).

Thanks it worked but what is the science behind that?

I believe it's because the fsgame.ltx file is in the game folder instead of the bin folder. When you launch the game through exe, it looks for the fsgame.ltx but can't find it because it's not in the same directory as the exe itself. When you change the start location to where the fsgame.ltx is located, it will load with no issues

For what I can tell, the xrengine.exe is just an engine file and it needs to have the game files pointed out to it, so that it can load them. The location of this files is what is in the fsgame.ltx file, which is in the base folder of the game installation.

Funny thing is that if you launch the game directly from the offline installer, it works properly. The shortcuts that are created are the broken ones.

Second funny thing I found out is that fsgame.ltx is installed properly by the offline installer, but just after the installation finishes, Galaxy downloads an "Update" that creates the other common error with the game, which is the duplicate entries error.

hi vlad
I have the same problem with Call of Pripyat.
After I changed the link as you wrote, the error with fsgame was solved. After that, the game wants to have a lot of dll files when running. When I add all of them, there is no error message at the end and the game still doesn't start. Do you know the error or do you perhaps have a solution?

thank you very much
