installation on VMware fusion on Mac

[dysong3]

I am trying to install FMS on a Windows Server running on VMware fusion on a Mac, but at the end of the process I get a message saying that port 80 is in use and that it must be made available for the installation to complete.  However I have run "Netstat -a -o" in Command Prompt and the only thing using port 80 as far as I can see is TCP. Is there a way around this problem?  If so, I would love to hear it.
