I right click on the file in Explorer and select extract. This opens B&R and a dialogue displaying two entries for the VM (I'm assuming this is because a snapshot existed when it was backed up). I select one of the entries (either one) in the list and click Restore. This gives me an option of restoring to Azure, Entire VM, VM Files or Guest Files. I select either Entire VM or VM Files and after a brief pause, receive the error mentioned above instead of the Full VM Restore Wizard.
