What do you mean that "the VMs are all gone"? If the VM list didn't display on the main page, you can open the VM by "File -> Open a VM".
Well, the emphasis should be on:
"all vestiges of VMWARE are gone"
Hard to deal with VMs without Player, eh?
So, there is no Main Page.
Can you give more details:
- Guest OS information
- Detailed steps about how to reproduce this issue. If you can't install the WS 14, what error do you meet ?
- ui log (should be under %TEMP%, you can get detailed log location under "Help > About VMware Workstation ")
The situation was fixed by running DISM and SFC.
