Unsupported Operating System (code 1709)

Description Value
Issue ID 1709
Issue Class Error

Situation

The restore plan terminates with the following error: Unsupported OS (Code 1709)

Cause

The restore plan has the Convert GPT to MBR feature enabled. This feature has several limitations, in particular, related to the Windows Management Instrumentation (WMI) feature and toolset. The occurrence of error 1709 means that the Windows version of the instance where Backup for Windows is installed does not have a sufficient WMI kit to support the Convert GPT to MBR feature.

Solution

  1. Make sure the Convert GPT to MBR feature is required for this restore plan. To learn more about this feature, refer to the Convert GPT Disks to MBR chapter of the help documentation.

  2. Install the application on an instance with any of the following operating systems:

  • Standalone Platforms:
    • Windows 8.1
    • Windows 10
  • Server Platforms:
    • Windows Server 2016
    • Windows Server 2019
