The error arises from the installation of BDRShield client on an OS other than the host OS or when the Hyper-V Role is not enabled.

To resolve this issue, follow the steps below:

Enabling Hyper-V Role:

1. Log in using an account with local administrative privileges and open the Server Manager by entering the `ServerManager.msc` command in the server’s Run prompt.

2. In Server Manager, right-click on the Roles container and choose the Add Roles command.

3. Select the Hyper-V checkbox in the Add Roles Wizard and click Next.

4. Choose the physical network adapter for the virtual network adapter and click Next.

5. Confirm your selection to install the Hyper-V role and click Install.

6. After installation, click Close and reboot the server if prompted.

Configuring Backup for Hyper-V Guest OSes:

1. Display a list of features and their status using the command: `DISM /Online /Get-Features`

2. Enable the `NetFx2-ServerCore` feature: `DISM /Online /Enable-Feature /FeatureName:NetFx2-ServerCore`

3. Enable the PowerShell feature: `DISM /Online /Enable-Feature /FeatureName:MicrosoftWindowsPowerShell` (Ensure 'NetFx2-ServerCore' is installed first to avoid errors.)

4. Reboot the machine.
