I'm trying to install Sage 2020 Quantum on Windows Server 2012 R2.  I have an existing version of 2019 Quantum already installed and it's working fine but now I'm getting issues on the workstations stating the serial number I have is already in use.  I called up tech support and they stated that my serial is now a 2020 version, so they suggested I upgrade to 2020 to fix the error.

I downloaded the 2020 installer and try to run it on my fully patched (as of 8.27.2019) Windows 2012R2 server but it states the following:

This release of Sage 50 does not support your current operating system.  Either install the latest updates or upgrade to a supported operating system.

Review the system requirements at:

I went to that URL and it says Server 2012 but not 2012 R2, so I guess it doesn't support it? It makes no sense to me.  I tried using run as compatibility option for the setup.exe but it still spits out the same error message. 

Has anyone tried installing 2020 Quantum on Server 2012 R2?
