On a certain page I want to check if my dll exists on the client page or not, if it doesnt then˙ they should be directed on the page so they can download the dll. Also tell me how do I get that dll registered on the client pc? For example when we go to have msn chat, it stops us on the page to download the component first, and when its done it takes us to the chat page, we dont have to do any sort of registration.
