What does "not work" mean? Does the code run at all? Does the application run at all? Does the application run but not produce the result you expect?

What's the use? How can you make sure the user has the volume D? There are no cases when hard-coded path name could be useful.
And starting the process is much simpler:
System.Diagnostics.Process.Start(yourFileName);

Web based application uses Server.MapPath[^] method to define path to the file(s). On the other site, have a look here: Process.Start[^] method:

MSDN wrote:
Note

ASP.NET Web page and server control code executes in the context of the ASP.NET worker process on the Web server. If you use the Start method in an ASP.NET Web page or server control, the new process executes on the Web server with restricted permissions. The process does not start in the same context as the client browser, and does not have access to the user desktop.

Please see my comment to the question and the original documentation: http://msdn.microsoft.com/en-us/library/system.diagnostics.process.start%28v=vs.110%29.aspx[^].

As to the paths to some files, they can always be calculated during runtime, based on user input or some configuration files. You cannot just use hard-coded drive "D" (or "C", does not matter) — who knows what is it on each particular system? Not all system have D, not all have C (it may come at surprise for you, but this is so). For some valid directories you can use, please see my past answers:
How to find my programs directory (executable directory),
How to find my programs directory (current directory, "special folders").

Besides, it's generally not a good idea to start a separate process at all. Processes are well-isolated and usually not designed to communicate.
