>James,
> I know what was the problem. I have a Page1.ASP that has the function. When a link is clicked on this page, it was supposed to call this function but it failed. Before I ran my new setup.exe, I changed the Page1.ASP to call Page2.asp and create the COM Object on Page2.asp. And everything works. My next question is do you know a way to do this without having the Page2.asp? Thanks for all the suggestion.

Are you saying you want to create the object before the page is redirected? Why not create the object when the page is shown?
