Same question but with more explanation?

Question

I want to run a specified executable file on the client side

Answer 1

By design, Web pages cannot execute programs on a client''s machine.

You can do so via an ActiveX or Java applet. However, both will warn the user that you want to do so and both will require the user to actively approve the request.

You may be better off simply making an ActiveX / Java applet to do what you want.

Answer 2

No client will allow to execute a file. It can be harmful. What u can do, is provide a link on the page where the client can download and run the file. But u cannot run a file on client side automatically.
