That fixed it. Thanks for the advice and help! Much Appreciated.
As a note, I was trying to re-install Nero actually as it suddenly "refused" to "save to hard drive" when I attempted to save some Audio tracks on the HD for later listening.
As Nero did not want to save, I thought that Nero was buggy so I deleted it and went for a reinstall when I ran into the install problem.
The real reason why Nero did not want to "save to hard drive" as I found out later, was that my hard drive was full and had no space to save to!! I guess it would have helped if Nero had a little dialogue box that said – Hard Drive Full, Cannot save or something like that.
