Windows Server 2012 R2 Essentials Restore fails to Mount

I'm setting up Windows Server 2012 R2 Essentials for the first time. I'm able to backup a test client which runs Windows 7 Ultimate. All available Microsoft Updates have been applied to both client and server.

When I attempt to restore from a backup using the Windows Server Essentials Dashboard on the client machine I get an error stating the restore has stopped working.

I'm also seeing two errors in the event log.

Error #1

I found some old reports from last year stating windows update KB3023562 was the problem, but there was no change after uninstalling the patch. I also tried turning off the firewall on the client and server, but that changed nothing. I have done a repair on the backup database and no errors were found.

I've never successfully mounted a backup, so I'm not sure what the problem could be.
