Hello, I just upgraded from 1940 to 1966, and the new shared networking option is grayed out in my XP VM. Here is my upgrade procedure: Uninstall 1940 using the uninstaller. Reboot. Install 1966 using installer. Reboot. Fire up the VM, install Parallels tools. Reboot VM. Shutdown VM. Go into options, shared networking is greyed out. I do not have internet sharing enabled on my Mac. Any ideas as to what could be causing this?
