Application crashing on startup using Process.Start

Question

I have the following code:

var psi = new ProcessStartInfo();

psi.FileName = @"C:\gw\gw.exe";
psi.WorkingDirectory=@"C:\gw";

Process process = Process.Start(psi);

For some reason, the gw.exe process is crashing on startup. Windows just says "This program has been shut down" and has the usual "Looking for a solution online" box and it just crashes.

When I launch gw.exe from Windows explorer, it executes just fine. It is a WPF application and it runs just fine outside of my program. Anyone have any suggestions?

Have you checked the windows event logs to see more details about why the application is crashing? — Jason Down, Jan 04 '12 at 00:27
Have you tried initializing psi.Arguments to something instead of leaving it uninitialized? — Mike Nakis, Jan 04 '12 at 00:28
@JasonDown - I have looked at the logs, but nothing useful. This is what it shows: Fault Bucket, type 0 Event name CLR20r3 Response not available Cab id:0 — Icemanind, Jan 04 '12 at 01:23
There are other DLLs this program relys on to run. They are in the same directory as the application. I am setting the WorkingDirectory property. Could this be an issue? — Icemanind, Jan 04 '12 at 01:38
What if you run this through the debugger or use a try/catch. We need to know what the error is to really address the problem. — Jason Down, Jan 04 '12 at 02:31

Your code is not how one starts a process:

Console.WriteLine("Running"); 
Process pr = new Process(); 
pr.StartInfo.FileName = "Notepad.exe"; 
pr.StartInfo.Arguments = "test.dat"; 
pr.Start(); 
while (pr.HasExited == false)     
   if ((DateTime.Now.Second % 5) == 0)     
   { 
      // Show a tick every five seconds.         
      Console.Write(".");         
      System.Threading.Thread.Sleep(1000);     
}

Trying this code produces the same problem – Icemanind Jan 04 '12 at 01:19
Does it run notepad.exe though? – ΩmegaMan Jan 04 '12 at 01:29
Yes, it runs notepad just fine – Icemanind Jan 04 '12 at 01:33
Copy the program to where gw.exe is and run it from that directory. – ΩmegaMan Jan 04 '12 at 01:48
That worked OmegaMan. For some odd reason, the executable has to be in the same directory as the executable I'm trying to call. That is wierd, but its okay for me because they are both going to be in the same directory anyway in the end – Icemanind Jan 04 '12 at 01:50
Set the process working directory http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.workingdirectory.aspx – ΩmegaMan Jan 04 '12 at 01:54
OmegaMan -- I'm doing that...See my code snippet above in my question – Icemanind Jan 04 '12 at 01:57
