People, I just ran into this same problem.
I couldn't install VMware bridge protocol, but the actual problem was that I couldn't bridged vmnet0.
I spent about 5 hours trying to solve the issue.
Then, reading your replies, I just clicked the Restore Defaults button on Virtual Network Editor and it worked !!!
Of course I had to reconfigure all my network settings, but in my case I had the default (3 adapters).
Now I can bridge my vmnet0, and it was not necessary to install the vm bridge protocol.
Hope this help.
I managed to solve this problem.
In my case problem was ZoneAlarm, it prevented from adding Bridge protocol to network adapter, even if I was logged in as Administrator. I uninstalled ZoneAlarm, reinstalled VMWare player, adapters appeared on the list, so I installed ZoneAlarm again and voila!
I hope it will help you as well.
