[DUG] Com support

Tue Jul 31 11:28:02 NZST 2007

Further to the stuff below just tested it on a Third machine and no go 
also on that machine (but it still works on the other dev machine).

My machine (D2007 windows vista) - Fails
Other Dev Machine (D2007 Win XP) - succeeds
Other machine (No delphi, Win XP) - Fails

Clients machine Win XP - Fails
