I did not run the clean tool as this was not mentioned in the install instructions. I did have a previous edition of Nero, removed this using Add/Remove
I will remove this copy and do as you suggest.
Many thanks for your advice

Startsmart failure
I had the same problem. I uninstalled Nero 8, deleted the Nero folder and ALL of it's contents under c:\program Files\Nero.( including stuff left behind from Nero 7) I also deleted any Nero icons from my desktop. I then went into msconfig and turned off my UAC for Vista. I then rebooted as required. I then tried to reinstall Nero 8, which asked for another reboot, which I did. Once I was rebooted a third time, I shut off my anti virus and allowed Nero 8 to continue it's installation. What I noticed different this time around with the UAC shut off was that after rebooting, Nero 8 RESUMED it's installation by itself, something it did not do the first time I installed it. I now have no problems whatsoever with Nero 8. I hope this helps others with the same runtime error that I had.
