This article applies to:

  • OS: Windows 7, 8, 8.1, 10

Problem description

While performing a re-installation or an upgrade of inSync Client to a higher version, the installer may display the following error:

The older versions of Druva InSync 5.x cannot be removed. Contact your technical support group.



The error is displayed as the device registry continues to hold the registry key of an older inSync Client version. 


  1. Download  and run the fix provided by Microsoft on the affected machine. Download the patch from the link: Fix problems that block programs from being installed or removed.
  2. Retry installing inSync Client. If the installer continues to show the error, perform the next steps.
  3. Check the Event ID 2002 in the Application Log on the affected device.

  4. Note the registry key shown in the event.

    Note: The GUID is different for every version of inSync Client. Hence, you must search with the key value found in Event 2002.
  8. Close the registry and again try to install the latest inSync Client version.
