Oh good grief!

This is a very common question, raised by people who have no idea what they are doing... When you execute the method Process.Start, is it executed in the code behind. Which runs on the server, not the client. So any process you start, and any executable file that runs, runs on the server, not the client. So your user cannot see it.

When you tested this on your local machine, the server and and the client were the same computer, so it looked as if it worked. It doesn't. There is no practical way to run programs on a client computer - you cannot even tell if the client is a PC, a MAc, a mobile phone or a refrigerator with internet access. Note that I say "practical" - there are a couple of ways to do it, but they all require the prior consent and enthusiastic help of the user, which is not going to be forthcoming in 99.999% of cases.

Drop the idea. It won't work.

Yeah.
I have the same problem.
I want to open the notepad with a message on the server and it refuses to do it!
It seems to be some sort of security measure. you need to grant more premissions:

As IIS is a service it is not running under a separate session - different from the one you are logged in, and under a different user account! So you can't see the application, even if it is really started. Still, there are only few situations when starting a process on server side from an asp.net application is wise - use this approach only when the application you start is command line application, and never requires user interaction to terminate (even with error condition).

The solution is that in the same situation if your application was deployed under iis 7.5 on Windows 7 it won't work; but if you deploy the same application under iis 8.5 on Windows 8.1 it will work 100% guaranteed. I have a MVC 4 application that calls a file.exe for pdf generation. The same deploy run under iis 8.5 on Windows 8.1 but doesn't run under iis 7.5 on Windows 7. It crashes in Process.start(). By few words IIS 8.5 is better than iis 7.5. This is the solution, but because of this I can't solve the issue with iis 7.5. It's not funny. I'll accept other solutions.
