I have Nero 7 Premium and I can't get it off my computer. I want to install Windows 10 and I must remove Nero 7.
Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
