You're trying to start a process of some kind which you can't do. Your .net code runs on the server and while developing on your local machine the server is also the client so your code appeared to do what you want (ie launch a task on the "client"), but when your code runs on a remote server then that is where the task is ran, not on the client.

You can't launch processes on the client for obvious reasons so you need to re-architect what it is you're trying to do.

You'd have to explain what it is you're trying to do, it might not be possible. For example you've mentioned downloads so if you're trying to save files on the client machine, or execute files on the client machine it's just never going to work.

I need to download some files text or pdf files from server which are stored in a specified folder. It needs to be downloaded to client machine on click of the button.

Google " download file to client" for sample code. Note that you can only instigate the download (ie the client will get the "Open or Save As" dialog), you can't make them save it or make them save it to a specific location on their drive.
