first try always work but i do it again gives error.if i restart computer it works then errors :(

do you have all the visual runtimes installed?
it could be that or antivirus or firewall
those 3 things i have seen cause this error
also sometimes certain compressor commands
do not miix well with eachother

probably my problem is that. where should I add it exactly?
-edit man thank you sooo much you helped me too much :)

In arc.ini

i have a problem in extraction :)) i can unpack with arc.exe -x option but if i use unarc.exe or inno setup, in task manager xtool.exe do not close himself, stays in background and i can't see finish page of setup.how can i unpack them with arc.exe in inno?

Use taskkill function

Hi everyone, does any of you have problems with files larger than 4GB?

In my case:
Game > Shadow OF Mordor
File > DLC2.arch05

Xtool hangs at the beginning of the decompression and giving CRC error. With FIles of the same type and smaller size I do not have the same problem.

Setting are: packcmd = XTool.exe e:precomp:c256mb,t4:zlib - - <stdin> <stdout>

Try t1 parameter for unpacking.

maybe you have problems with srep no xtool. you can put the file on the forum so I do that test. so we are not forced to download the whole game

Thanks for the reply. You're probably right. I use Srep 3.93 x64 version which would seem to have a bug. Unfortunately I can not recover version 3.92 which would seem to be more stable.

Can someone tell me where I can download it?

here is srep 3.92 beta

i don't have those games :(

Sure, pak and ff samples from those games would do.
Also if possible, CODWWII, I have this game but I don't feel like installing...

Thank You.
