Thanks for your help Bob!

One question, how do you reference (in VS.Net) an assembly if it is installed in the GAC? From the component list I can't browse the GAC or the things that are installed in it. Would I have to install the assembly in the GAC and also put the assembly DLL's in a common folder? Thanks again!!

>The other option is to use the GAC. Your install script could ensure that the user has the common component in his GAC, if not, it would install it there. If course, you have to provide a strong name to put the component in the GAC, but that isn't very hard.
