Question

Why is this

ProcessStartInfo myProcess = new ProcessStartInfo(path);
myProcess.UserName = username;
myProcess.Password = MakeSecureString(password);
myProcess.UseShellExecute = false;
Process.Start(myProcess);

working, but

ProcessStartInfo myProcess = new ProcessStartInfo();
myProcess.FileName = Path.GetFileName(path);
myProcess.WorkingDirectory = Path.GetDirectoryName(path);
myProcess.UserName = username;
myProcess.Password = MakeSecureString(password);
myProcess.UseShellExecute = false;
Process.Start(myProcess);

is not.

I wanted to use the second one because of this question: https://stackoverflow.com/a/2621943/1306186

I am constantly getting a file not found exception… Any ideas?

Edit:
Path is for example @"C:\Users\User\Desktop\ConsoleApplication2.exe"

This bit is wrong

myProcess.FileName = Path.GetFileName(path);

this should be

myProcess.FileName = path;

Pass in C:\SomeDir\SomeApp.exe and the code you have will set the filename to SomeApp.exe, which it can’t find. Count yourself lucky, there are circumstances where it could have (e.g. your app and the app you want to run being in the same folder), and then you would have possibly got a funny when deploying.
