Ran an installation of the new Odyssey repack by Fitgirl 2 times. Both times i got an ISDone.dll error at 92.7% saying "An error occured when unpacking! Unarc.dll returned an error code: -1 ERROR: archive data corrupted (decompression fails)". I had the ram limiter box ticked and ran the installation on windows 7 compatibility. Was the windows defender the problem. It was on when i did both the installations. Also i ran a recheck on the torrent and apparently it came out at 99.9 percent(1.1mb remaining between some files). Could that be what caused the problem?

The first is that the failure description contains a CRC Checksum check error message. What does this mean? Only that the requested archive is damaged. Incidentally, the cause of the failure is also described: Unarc.dll returned error code 12. How to fix this situation? Yes, it's very simple. If such a failure occurs, then, the archive is simply nedokachan, so it is worth looking for another version of it and downloading it from another resource. You should also pay attention to the fact that the archive file may actually be corrupted. The solution is the same.
But not everything is so simple. The fact is that the failure of "Unarc.dll returned an error code of 12" may appear in another very trivial situation. The fact is that some repacks with games and patches, which are "cracked" versions of original distributions, do not allow unpacking or installation in folders whose names or in the indicated ways contain Cyrillic characters.
There is another case when a failure occurs with the message "Unarc.dll returned error code 12". It may be due to the too small size of the paging file or its disconnection in the system. It is clear that you need to enable it and adjust the size.
Finally, another problem with the fact that a failure occurs, and the message indicates that Unarc.dll returned error code 12, may be due to incorrect operation of the RAM (too strong and unreasonable load, physical damage, etc.). . Although this situation is rare, it can not be discounted.
