Server 2012 woes

I have UrBackup running on many versions of Windows including various servers and it runs flawlessly. Makes Veeam Endpoint seem like its eating crayons in comparison.

The one sticking point is Server 2012 R2. I have a couple of these bare metal boxes left, and they are fairly critical. Urbackup client installs fine, locates my Urbackup server, but then pukes. VSS writers seem fine and a Windows server backup works, but those are ckunky and not reliable.

Any ideas, or ways to enable more granular logging to troubleshoot this?
