This is by way of a 'heads up' really.
I originally had problems when I upgraded from Nero6 to Nero7, but after a complete clearout got it working, eventually.
Yesterday I decided to install the 7.0.8.2 version over the existing 7.0.5.4 - and I wish I hadn't bothered.
I may have got a corrupted download, i suppose, but on rebooting after an apparently successful installation, I received several 'damaged installation' messages, that prevented running any Nero services.
I did a full uninstall, using the Nero 'cleaner' program, as well, to be sure - but reinstalling gave the same issues.
For now, I have gone back to the 7.0.5.4 version, with no problems.
As I say, it may be a corrupt download (and at over 100Meg I'm not too fussed trying again, at this point
), but I thought I'd post this, so anyone else having the same issue will know it isn't just them.
