Running an exe from Web Server to Client System

I have an normal exe at my web server . I want to get it download from my server to client from a web page and run at client side . But i dont want to show dialogue box to save it on disk or run from server etc. While click on download link it should automatically download at client at get executed . How it can be done , is it poss through normal exe or i have to use some active - x exe . actually my purpose is to install a program at client machine from my server but there should be no download/Install option . it should be done silently in a webpage.Once it installed i can show the user the required page .. any one has tips or suggestion for it ?????

but there r lot of sites which does such type of installation .. like downloading and resgistering active-x controls/components ..
i also hv to do tht .. ergd security all our controls n components r signed by verisign ... this is some what CAB deployment and download but in my application there are lot of other things so i want to install in my own way...

ActiveX is a totally seperate technology. If you want it to automatically download, them embed an ActiveX in the page. You can then get your ActiveX (once its installed and running) to download the EXE.
