Firstly let the installer rollback and reboot, then run the
setup.exe rather than let it autorun ensuring that it's ran as
administrator.
If that doesn't work then make sure that the 'COM+ System
Application' and 'Distributed Transaction Coordinator' services are
running, if they weren't switch them on and try again.
If you still get no joy then delete the registry key
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\COM3' then reinstall 'Component
Services', reboot and try again.
If they don't work then I guess you might need to call VMWare ok, good luck
