There are 2 posts around that mention Nero Temp file cleaning. I can confirm that CCleaner does indeed delete these files and then Nero 7 Premium won`t work after that. There does not seem to be a workaround to avoid this so I can not use CCleaner in it`s present state. Can I suggest for the next version a folder exclusion option is built in so that I and others may exclude the Nero Folder from being emptied?
