Sims 3 v1.22.9 File Archive corrupted
 

The structure of the archive is damaged (Error #17540)
Any way this can be fixed? or opened another way? I'm using Stuffit to open it.

There's nothing wrong with the archive. StuffIt is for the Macintosh, who knows how well it can handle PC-related archive formats, so get WinRAR instead.

unrar on mac the same as linux only support commandline. I guess they should have some gui frontends as we have on linux or just type on console

unrar x and paste the name of the file
