The Adobe Creative Cloud Desktop app displays a "You don't have access to manage apps" message

To fix this on Windows: 

• First sign out of the Creative Cloud Desktop app, then close the application
  
  
• Navigate to:  C:\Program Files (x86)\Common Files\Adobe\OOBE\Configs
  
  
• Rename the file called "ServiceConfig.xml" to "ServiceConfig.xml.orig" (Right-click and select "Rename")
  
  
• Download this replacement ServiceConfig.xml file, and copy it into the "Configs" directory (same directory as the original file)
   
• Reboot your computer
  
  
• After rebooting, re-launch the Adobe Creative Cloud desktop app, and you should no longer get the "You don't have access to manage apps" error.
