I've just done a fresh install of Vista Ultimate on my home machine, done the windows update thing and I've tried to install Nero on it. Nero keeps telling me that the copmputer needs to reboot before the installation can continue.

Once I reboot the computer and go through the Nero install again, it tells me it needs a reboot. wondering if it was just Nero being a pain, I then tried to install Symantec Endpoint Protection on the computer and that tells me that a reboot is needed before it can continue.

I haven't added any hardware or installed any software except for the updates.

Does anyone know of a issues with any of the Vista updates that would cause this??
