I have Nero 9 Reloaded (DVD From Amazon) installed and updated OK, then i tried to install InCd, but it gets to a certain point, then i get this error message saying- "Error 1721, There is a problem with this installer package, A Program required for this install to complete could not be run, Contact your support personnel or package vendor, Action: CleanupNBHregInCDSrvDb, location: ...\NBHRegInC...

Anyone help on this please?

I had the trial version of Reloaded and InCD installed previously, but uninstalled before installing new disc, and used Nero Clean Tool & a Reg Cleaner.
