Has anyone tried installing SW PDM Standard 2016and/or Workgroup PDM 2016 on Windows Server 2008?

The system requirements on the website show Windows Server 2008R2 as a tick, but Windows Server 2008 as a Red Cross.

I wondered whether the red cross meant 'Not Supported' or 'Does Not Run'.

Our server admin is not inclined to update the server OS, but we want to move to SW2016 and PDM Standard.

Cheers,

John
