I recently tried installing Roxio Easy CD Creator 5 basic (the free version that came with the computer) on my laptop. The laptop had a fresh install of Windows XP on it a few months ago, and I am just now getting around to reinstalling Roxio. During the install, the system crashed and rebooted. When it came back up and I tried installing again, a dialog box came up stating that the software was already installed and it wouldn't let me go any further. The software doesn't show up in add remove programs, so I can't uninstall it. Does anyone know of a registry setting or even the exact file that makes the wizard think it is installed so that I can delete it?

Try removing the Roxio folder from Program Files and the Roxio key in registry under HKLM\Software
