I need a copy of the big 600+ MB complete 8.4 tar file for both Cos5 i386 and x86_64. I need this to fix broken upgrades to 8.6 since upgrading 8.4 to 8.6 only works half the time. I used to just download it from the download1.parallels.com server as needed but it appears directory indexing has been disabled and I can't come up with a working guess at the location of 8.4.
