I downloaded the trial version of Disk Director and it installed and worked fine. I then purchased Disk Director 10 and the installer will not launch when I click on it. I have tried installing over the trial version, as well as uninstalling the trial version and trying to install from scratch. The behavior is the same. I have tried this on three different PCs, with the results being the same on all. I am running Windows XP SP2 on each of my PCs. Can someone please help?
