  I am trying to get a third-party backup solution that takes snapshots of running Hyper-V Virtual Machines working.  It is on a Microsoft Windows Server 2008 R2 machine, we have found hotfixes for the non-R2 version of Server 20008, but nothing that works in this version.  When I list out vssadmin list writers I get the following:

  I have sent this to the support provider for that company's software and they tell me that I am missing the "Microsoft Hyper-V VSS Writer."  We have successfully got the software to work on a number of other servers and those do have this writer.  My question is how does one get it enabled/running. I had found a set of commands to run to fix various VSS issues with a different company's software and it also did not work:

  net stop "System Event Notification Service"
  net stop "Background Intelligent Transfer Service"
  net stop "COM+ Event System"
  net stop "Microsoft Software Shadow Copy Provider"
  net stop "Volume Shadow Copy"
  cd /d %windir%\system32
  net stop vss
  net stop swprv

  Any help would be much appreciated.
