Hello
Use ClickOnce.

You will need to create a console, winform or wpf project and publish it using clickonce.

Once you have a working program that does what you want (ie opening windows explorer) you can redirect from your asp.net site to the clickonce url:
HttpContext.Current.Response.ContentType = "application/x-ms-application"
HttpContext.Current.Response.Redirect(url, False)
HttpContext.Current.ApplicationInstance.CompleteRequest()
This will download your program, pass what ever parameters you need in the query string and that's it.
