I have a windows 8.1 guest and I can't install vmware tools on it due to our security policy. But I can install the display adapters only, if this is possible. After reading about it I understand that the display adapters are in VMware SVGA 3D (WDDM) driver.
Is this the right driver that will allow me to use display with a resolution larger than 640 X 480 and 16-color graphics?
Is there a way to install the VMware SVGA 3D (WDDM) driver without installing vmware tools?
You could try this:
Invoke the setup64 from a command line prompt (instead of just double clicking on setup64) after invoking Install VMware Tools from the menu
It will prompt for a folder location to extract to without installing VMware Tools.
The video drivers should be in <extract location>\VMware\VMware Tools\VMware\Drivers\video_wddm\Vista
So you could try manually installing the video driver from Device Manager (or whatever method you choose).
