Multi Install and Update Problem

Thats the error message i kept getting Fuse. I tried the copy and paste of the Wow.exe .... didn't work for me. But the downloading the patch file into each folder sounds like the answer, next time.

I read somewhere here that you should remove the junction then patch then rejunction
or
if already stuffed, remove the junction and reapply junction
