If your on vista go to the search bar and type installer. A folder will pop up with a bunch of installers. Right click the top bar and click "more", scroll down and find "subject" and put a check next to it and press ok. Then scroll through the list while looking at the subject section and you should find the one for nero. Right click it and press uninstall. That should do it. If you get an error, let us know what it said.
