For WS 11.1.0 you can silently install Workstation with the keyboard driver by using this command line:
VMware-workstation-full-11.1.0-2496824.exe /s /v EULAS_AGREED=1 SERIALNUMBER="123-456-789-123-456" ADDLOCAL=ALL REMOVE=""
Unfortunately, since the Keyboard feature is disabled by default, the bootstrapper automatically passes REMOVE=Keyboard to the MSI. That means that even if you pass ADDLOCAL=ALL the Keyboard feature will still be bypassed. Passing REMOVE="" will clear the REMOVE property so that the Keyboard driver will be installed.
