@testDummey: Thanks for the reply.

Re:1.
I am looking at install shield to see if there is a way to change icons during install. I am puzzled that the Pro version does not seem to comfortabley accomodate this when publishing Pro content.

I recall trying to use an icon changer of some kind before and it appeared to currupt the exe. I will look at the software you suggest.

Re:2
I presume you mean a custom .dll. I will investigate this further.

Re:3
That's going to be somewhat problematic. Thanks for the concise reply.

Re:4
I am sure that when we are close to final publish, we can discuss with Conitec much of the legal implications and come to some amicable arrangement.

Re:5
Looks like another 'support' type enquiry then. Indeed the time for flinging the preverbial faeces around is not now

Thanks for all your help testDummy, much for us to investigate later.
