Yea, so I finally got my MSFN account created. Today (or Sep 14, 2020, which is 2 days before) is a sad day for a Vista user on VMWare Workstation Player.
VMWare Tools 11.1.0 is no longer supporting Windows Vista SP2 and Server 2008 SP2, according to this documentation. https://docs.vmware.com/en/VMware-Tools/11.1/rn/VMware-Tools-1110-Release-Notes.html
What's more by adding salt to the wound, I just updated VMWare Workstation Player to 16.0.0 today, with corresponding hardware version number updated (by modifying .vmx file, changing virtualHW.version variable to "18"). Then I've found out DirectX 11 virtual hardware cannot be equipped on a Windows Vista guest, despite it supports DX11.
I guess this is a farewell from VMWare dev team to Windows Vista. Those who run Windows 7/8/8.1/10 and corresponding server builds on VMWare Workstation as a guest could celebrate and cheer for DX11 support, but that party door shut for Vista / Server 2008 original users permanently.
Here are some additional information on DX11 support for VMWare Workstation 16: https://blogs.vmware.com/workstation/2020/05/directx-11-now-with-workstation-tp20h2.html
