Vista - Meeting Space won't launch

When I go to start Meeting Space, only 'People Near Me' opens and connects,
but the window to control Meeting Space doesn't open. I've ensured that
IPv.6, Peer Name Resolution Protocol, Peer Networking Grouping, Peer
Networking Identity Manager and DFS Replication services are running - and
the firewall has Meeting Space enabled. I've also tried to uninstall and
reinstall the program, but nothing works. It's the only thing that 'isn't'
working. Can anyone give me a step-by-step method of using WinPE to possibly
replace / restore whatever is required for Meeting Space to run?

Thanks!
