I have installed this Brother MFC on several Vista Biz workstations, but one. This just so happens to be the one guy that doesn't have admin rights to his machine. I run every wizard as administrator, and put in the credentials, and the printer seems to install just fine- find it the directory, install driver, select default, test page, and finish, but no printer. Where did it go? I try to install it again, but it says it's already installed. And before the wiseguys jump in, yes, I've restarted.
