I bought this from it next and it's the 27.7 gb repack version from CorePack.

Now, while decompressing the part 24 and part 41 I got crc error. No error was shown when decompressing the remaining 39 files btw.

Anyway, when installing the game I got ( isdone.dll and unarc.dll) error which r usually shown if there r corrupted decompressed files in the installation directory. Can anyone help me here. Thx.
