So, on 4 computers I have now, half the time I try to update Im getting this: Error Code: 732 (0, 0) and cannot update.... After doing research, most people have determined that this is a problem with version 1.39, and was fixed in 1.40. I have 1.40. other people and admins say it has to do with the pro version of realtime protection, neither of which I have or use. Any ideas?
