I have a small chat program that I have finished...

I want to create the Smallest possible install.. and I dont want to use the P&D.

I am using the standard controls.. which I know need no install.. the exe will run on its own..
but I am also using the
INET (msinet.ocx .. do I need the oca file too?)
WINSOCK (MSWINSCK.OCX.. also.. oca?)
RTB (RICHTX32.OCX .. also.. include oca?)
controls as well...

do I need the oca's? and If I Include these in the zip...whats the best way to register them.. can it be done silently?

Thanks!
