Process.Start() not starting the .exe file (works when run manually)

Question

I have an .exe file that needs to be run after I create a file. The file is successfully created and I am using the following code to run the .exe file after that:

ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.FileName = pathToMyExe;
processInfo.ErrorDialog = true;
processInfo.UseShellExecute = false;
processInfo.RedirectStandardOutput = true;
processInfo.RedirectStandardError = true;                        
Process proc = Process.Start(processInfo);

I also tried with a simple Process.Start(pathToMyExe); but the .exe file is not run. When I try pathToMyExe manually on my Windows Explorer the program is correctly run. But not via the program. What I see is the cursor turning to waiting for a few seconds and then back to normal. So there are no Exceptions thrown either. What is blocking the file?

Answer 1

You are not setting the working directory path, and unlike when starting the application through Explorer, it isn't set automatically to the location of the executable.

Just do something like this:

processInfo.WorkingDirectory = Path.GetDirectoryName(pathToMyExe);

(assuming the input files, DLLs etc. are in that directory)
