I can't post a URL of a screen shot of the image because  I don't have personal website to save it to. Here is a description. When I download and try to run the setup wizard and initiate a scan a popup appears which says;

AVG Driver Updater Setup ended prematurely because of an error. Your system has not been modified (this is followed by instructions to run the wizard at a later date and how to exit the screen). There is nothing about the nature of the error.

Almost immediately another popup appears which contains a red circle with a white cross and the words 'unspecified error and a 'OK button to quit the Window. Nothing else

As requested I checked both machines to see if any other driver updater was installed on either but there is none.  FYI both machine have the version of Windows 10 that Microsoft supplied to update a pre-existing OS. In both cases the pre-existing OS was Windows 7.
