I'm developing in VB.NET on Windows 2000 Professional.  I have two versions
of.Net Framework installed: 1.03.3705 and 1.1

The software I create, when it is installed onto a target machine, it wants
to run the older version of the framework, not the newer version.  It also
blows up before the program even has a chance to load.  The title of the
error is "Common Language Runtime Debugging Services" and it says
"Application has generated an exception that cannot be handled", followed by
a Process ID and the Thread ID.

How do you make it work with the newer version of the .Net Framework?

App developed based on older version of .NET framework, in general, would
work on a computer with later version of .NET framework only, unless your
app uses some .net feature only available in older version (there would be
very few, if any). Since .NET is designed for different versions coexisting
side by side, so it is not 100% guaranteed that app developed on older
version of .NET would run OK on later version of .NET (even most likely).
You must test your app on later version of .NET by your self, or simply
installed the version the app is developed on. As I said, multiple versions
of .NET framework installation are desireable if you have to run app
developed on different .NET versions.

AS for your problem, if you are not willing to install multiple versions of
..NET, you sure need to test/debug your app on later version of .NET in order
to determine what causes the exception before send it to user with later
version of .NET only.
