I am having a problem that is listed as SOLVED, but I am having this problem, and can't use ZA as a result. I am using Windows Vista, and when I try to install ZA 10, after all Windows updates, I get a User Profile can't be found on all user profiles (I use an admin profile and then a regular user profile.) I am VERY frustrated, as I have used this in the past. I have had to go back to backups just so I could boot my computer. Finally, I wiped everything, and started from scratch, and the issue came up immediately. And when I say I wiped everything, I started from a clean Hard drive and a clean OS install.
My computer is on a LAN, but it's in house (personal only), and ZA is running on a Windows 7 computer and a Windows XP machine.
