Okay so I think at least this time I figured out which file is failing a crc check so now my issue is how would i address this problem?
I do have a backup of the original gog installer so i will install to a new folder then see if possibly by moving this file to the repack folder maybe it will fix the problem I think this is the best I can hope for or find a way to make the installer ignore the mismatch which could ultimately be problematic.
