RGU make a self-service Creative Cloud Client available to staff devices. This allows users to install and update Creative Cloud Applications within the Creative Cloud app.
Should a user contact the IT Service Desk and advise they are unable to update applications and are getting something like the screenshot above. Please action the following steps
1. Have them close down all Adobe Creative Cloud Applications, including the Creative Cloud client itself. Ensure this is not running in the background or on the menu bar running along the top of the screen.
2. Reinstall 'Adobe Creative Cloud Desktop' from the 'RGU Apps' portal on their RGU Mac.
3. Once installation is complete, launch the Adobe Creative Cloud Desktop App
4. The ability to install and update applications via the Creative Cloud Desktop App should have resumed.
Additional Troubleshooting Tips:
Should the above steps not correct this issue. Please utilize the Creative Cloud Cleaner tool. This cleans up corrupted installations of Adobe Creative Cloud and can fix
More details about the tool and when it should be used can be found here - Use the Creative Cloud Cleaner tool to solve installation problems
Once the cleaner tool has been run then have the user reinstall the 'Adobe Creative Cloud Desktop' app from RGU Apps portal.
I'd also note that the RGU Apps deployment is the same as the client offered by Adobe so should this be unavailable you can download it directly from Adobe - Download Adobe Creative Cloud apps | Free Adobe Creative Cloud trial
