Came across a potential stumbling block. When attempting to 'modify' the automatic updates setting, the installer choked when it was looking for the original "msi" file. I think it was because I've cleaned out the machine using a Cleaner type program that gets rid of unused and temp type files since the install of 4.6DM. So- just a heads up, in case you come across the same thing.
