My company produces IP Surviellance softwrae (CCTV, Access control etc)
and one of the features of our software is the ability to produce a CD
with all the images, together with a run time version of the viewer. The
intention is that anyone (the police) can insert the CD into any PC and
see the video sequence.

This all worked OK (ish) in VB6, but we always suffered from data access
components, DLL hell etc. We have now upgraded to VB2005 using .NET 2.0.

The problem is that our CD Viewer requires .NET to be installed on the
target machine and we can't rely on the end user having Internet access,
or Administrator rights, or the ability to pre-install .NET. I was
wondering if there was a way of producing a package with just the elements
of .NET that was being used, so that these could be written to the CD. Any
other thoughts?

You can run a little stub program to detect if .NET is installed, if it is
you run as normal, if it isn't you prompt the user to install it (ship the
runtime installer on your CD). If the user is motivated enough to run your
program, he will call his system administrator or make other suitable
arrangements - it takes 5 minutes to install and it's a 1-time thing. Note
that the .NET framework has been available for ages on Windows Update and a
lot of corporates have it installed in one form or another by default.

You might also consider another technology for this, such as a Flash
presentation (if it's just an image viewer) or simple web page.
