try do this
turn off your UAC then run the vmware workstation installer as Administrator
see whats happend.
if its not help you try enable system administrator and login with that and install vmware as normal and see whats happend.
please tell me if its help you.
in my idea windows 7 ultimate is better that home basic because home basic can handle certain memory and limited to few app run simultanious.
