Norton Corporate Update Problem

Hi all.

Norton Corporate downloads the update, but says installation failed. No Reason given. Have tried it many times, but cant understand why it won't install.
Any help please?
Many Thanks
Kenny

Try reinstalling Norton, other than that you may have a corrupted version

Have tried that. It has always been ok before. No problems and no changes since last time. Weird but very annoying as I need the latest defs.

don't know then - perhaps someone else can help

Thanks for trying anyway..:)
