Cause

This could be caused when a user attempting to upgrade or uninstall the Designer is not the one who installed it. For example 'UserA' installed a Designer version and now 'UserB' is trying to uninstall/upgrade it.

5. Delete the folder containing this. In this case, the folder with the name {E589....11} needs to be deleted.

If the Designer folder cannot be found in the above location, look for it in the following location: HKEY_CLASSES_ROOT\Installer\Products. Once the Designer folder is located, export it (to back it up) and then delete the folder. Thereafter installation can be re-attempted.

If the problem persists after deleting the folder as suggested, follow these steps:
 
1. Download the .diagcab file. This is a link to a Microsoft site, hence it is completely safe.  
2. Run the following command by opening command prompt using elevated privileges (i.e "Run as Administrator")
    msdt /cab <full path of downloaded diagcab>
3. 'Program Install and Uninstall Troubleshooter' will be opened.
4. Click next and choose 'Uninstaling'
5. A list of the program is displayed, choose, ‘Designer’ or ‘Doc1 Designer’ and select 'Yes, try uninstall'.
6. After this wait for some time as a tool will attempt to uninstall the Designer component installed.
7. Uninstall/upgrade again.
