I then logged in as the Administrator account (using runas didn’t work), and the install proceeded happily. I did have to update the local policy too. In desperation, I followed these steps to enable the builtin Administrator account (it is disabled by default on a clean install of Vista). The problem with installing Roxio is that the installer blows up with an error saying you must be an administrator to install the product. I was putting together a backup of my Documents and latest PST file, and there must be something funny about the files, but both the latter solutions croaked on them. Up until yesterday, I’ve resisted installing the OEM version of Roxio that came bundled with my Dell Optiplex GX620 workstation, as I found the combination of the inbuilt CD/DVD burning along with ISO Recorder handled all my requirements.
