Here's a pointer to an article that sums up the instruction: [Link]

And here's a step by step solution:

  1. Uninstall the Organizer add-in - [Instructions]
  2. Remove any other add-ins, since they will most likely be affected
  3. Open an explorer window to the ClickOnce cache folder, for XP: C:\Documents and Settings\<user>\Local Settings\Apps\2.0, for Vista and Windows 7, 8, 10: C:\Users\<user>\AppData\Local\Apps\2.0
    1. This can be a little tricky (at least in Vista & Windows 7) - here's some useful steps:
    2. Press the Windows button
    3. In the Start Search text box type Explorer, press Enter
    4. This will start a Windows Explorer Window
    5. In the Windows Explorer Address Box – the top text box, type C:\Users and press Enter
    6. Double click on your username
    7. Click on the Windows Explorer Address Box (like above), then add “\AppData” to the directory path, press Enter
    8. You should now be able to navigate to the folder specified above.
  4. Go to the 'Apps' directory and delete the '2.0' folder
  5. Reinstall the add-in
