C# 2.0 App referencing WMEncoderLib crashes instantly on Vista

[Paul Wolpe]

I have a very simple app written in C# with Visual Studio 2005 on
Vista. If I add reference to WMEncoderLib (<COMReference
Include="WMEncoderLib"><Guid>{632B6060-BBC6-11D2-A329-006097C4E476}</
Guid>) then as soon as I reference WMEcoderLib on Vista the app
crashes. No exceptions, just dead.

This applies even when I run the command line app from a cmd window
that has been run as administrator.

namespace Boom {
static class Program {
static void Main() {
new WMEncoderLib.WMEncoder();
}
}
}

Any ideas on what is going on here and how this app can be run?
