Hi Mike I already read your article it helps i already registered my dll in my computer maybe the problem is in the server maybe what i need to do is to remotely registered it in the server any idea. Thank you very much.

If the server can't create the object then it is not registered with COM. You must strong name the server object put it in the gac and register it with COM using regasm. Please look at my article on the topic I'm pretty sure it will help you.

You need a COM callable wrapper (CCW) in your C# dll. Then it becomes accessible from javascript or vbscript. See my article on the topic. Best
