I have a Toshiba Satellite (laptop) with XP Home installed on it. It did not work well, so I ran the backup disks today, and it seems more stable. HOWEVER, whenever I try to install the upgrade to XP Professional I get the error message: Setup failed to locate a valid qualifying product on your machine. Then it gives me a drop down window to select the drive that the qualifying package is on (c, of course). I select the C drive and get the error messate: Error 1688. Setup unable to locate qualifying product. What am I doing wrong? I have, indeed, registered everything with MS and with Toshiba, so what is the holdup?
