Bad archive on wii iso files

I just downloaded some wii ISOs (trivial pursuit: bet you know it, super mario all-stars, Just dance 2015, and you don't know jack) and none of them were able to extract from the .rar. To be sure it wasnt something on my end i downloaded multiple times but still was not able to get a working file. I tried multiple programs as well and one asked for a password or keyfile upon failure; are there passwords or keyfiles for any of these archives?

If your WINRAR is not v.5.0 or higher, it is on your end. Update it, and it will extract. If you're using other than WINRAR, get it, cause not all extractor program supports latest RAR5 algorithm. But if you're already using the latest WINRAR, make sure the download was 100% completed. And it that too been fulfilled, only then maybe the file is faulty.

Glorious! All files extracted after update. Thanks a lot
