Port Conflict

I am using Rockwell Software BOOTP/DHCP tool which require port 67 to open however it looks like port 67 is used by "bdservicehost.exe" so that doesn't allow me to open my software. I had to remove my antivirus to make it work one time however I can't afford to do that all the time.

How do I change bdservicehost.exe port from 67 to something else? Or How do I somehow allow my software to use port 67 as and when require?

Thank you
