Update error 0xc1900209--Need to uninstall unfindable software

Hi, Have you searched for a cleanup tool or uninstaller specific to this? I had a quick look, but didn't find one. Have you ever had it installed - or any Roxio product?

You could install the program, then uninstall it with (e.g.) Revo uninstaller.

If it was uninstalled recently, you could use a restore point created before you uninstalled it, then uninstall it using Revo uninstaller or Geek uninstaller, which scan for leftovers. However, it sounds like that's unlikely to be so.

With a partly uninstalled program, I would normally try to point Revo uninstaller at any remaining exe files, and force uninstall using that. But that's only useful if you can actually find any related exe files.
If you had this program installed, you could try installing Ultrasearch, letting it index, and try a few searches for folders related to this. If you can find some exe's you can use the force uninstall method.

Another approach again using Revo is to see if it's still listed as an installed program (although I think you'd be very lucky). If so, you could then uninstall it with a scan for leftovers.

Beyond that, lacking exe's or a restore point, you're probably down to trying to remove entries from the registry, something I've had to do a couple of times over the years.
Whichever approach you use, back up before you do.
Regscanner (free) is a convenient way to search the complete registry for all matching entries found.
