Normally this error message will occur if you have installed Vembu VMBackup client other than the host OS, or the Hyper-V Role is not enabled.


If this role is not enabled, please enable it by following the below steps:

Step 1: Log in using an account with local administrative privileges, and then open the Server manager. You can access it by entering the ServerManager.msc command at the server’s Run prompt.

Step 2: When Server Manager opens, right click on the Roles container, and then choose the Add Roles command from the resulting shortcut menu. Windows will now launch the Add Roles Wizard.

Step 3: It will prompt you to select roles you would like to install. Select the Hyper-V check box, and then click Next.
