App updates work but CC Desktop failes to update, error 191
I have used Creative Cloud for some years, and periodically the app updates withiut issues, until the latest occasion (probably between 31st July and today); while the app updates (Photoshop, Lightroom, CameraRaw) install as normal, Creative Cloud itself fails to update with error 191. This happens on two different PCs. I have looked through the suggested solutions and tried those that were plausible to no avail, and tried the "repar" option offered when uninstalling the app, which also didn't help. My version of Creative Cloud Desktop is shown as 6.7.0.278, dated today.
The log file mentioned in the "advanced troubleshooting" section shows the following:
FATAL: Error (Code = 191) executing in command 'AddUWPAppxCommand' for package: 'AdobeNativeClient', version:7.0.2.14
FATAL: Error occurred in install of package (Name: AdobeNativeClient Version: 7.0.2.14). Error code: '191'

That Windows error code means "The package couldn't be found.
You may get this error while removing a package that isn't installed for the current user."
It isn't a privilege or directory access issue (nothing has changed since it last worked) nor is it connected to where new apps etc are saved (on one of the PCs this is C: as it is the only drive); it appears that there is a failure to download the Adobe Notification Client.
Can anyone suggest a fix, please, or acknowledge that it is a bug?
