Nostalrius Begins - Quality wow vanilla realm (1.12)

For some reason, when extracting all the data files from Nostalrius-WoW-Classic, WoW-1.12.1-Setup-2.bin and WoW-1.12.1-Setup-3.bin fail to copy and I get an Error 0x80004005 code.

Anyone have any idea how to fix this?
I googled the code number and it's generally associated with corrupt files, though WoW-1.12.1-Setup-1.bin copied over fine.

I was thinking of getting a friend who successfully configured Nostalrius to share their .bin files over mediafire but I just kinda want to make sure that it isn't something else causing this issue.

Appreciate any responses.

your download was corrupted.

easiest to delete that package and download a new one.
don't share .bin files since they can be different version / sources.
