My updater cannot close my main program (C #)

I have an updater that is called through the main program after detecting the update (from a remote XML file), it first checks if the process is open

if (clsProcess.ProcessName.ToLower().Contains("conkinator-bot.exe")) { clsProcess.CloseMainWindow(); return true; }

(this starts for each process until it finds it (foreach loop))

the updater downloads the file:

 client.DownloadFile(url, "Conkinator-Bot-new.exe");

and then he tries to delete the current one and rename it:

 File.Delete("Conkinator-Bot.exe"); File.Move("Conkinator-Bot-new.exe", "Conkinator-Bot.exe");

but the error I get when this happens is the following:

Unhandled exception: System.UnauthorizedAccessException: denied access to the path "D: \ Conkinator Skype Tool \ Conkinator-Bot.exe".

however, a new version of the program is being downloaded.

Just because the main window is closed does not mean that the process is complete. You need to wait for the process to complete after closing the main window:

 clsProcess.WaitForExit();

Ideally, you should use a timeout - there may be something that prevents the window from closing, or the process may have a faulty exit mechanism.

It is much easier to close the main program from the main program itself.

  string msg = "To update the application we need to close it. Do you want to continue?"; if (DialogResult.Yes == MessageBox.Show(msg, title, MessageBoxButtons.YesNo)) { ProcessStartInfo psi = new ProcessStartInfo(); psi.FileName = "YourUpdaterFile.exe"; psi.WindowStyle = ProcessWindowStyle.Normal; // Assuming a lot here but to just show the options available.... psi.WorkingDirectory = Path.GetDirectoryName(Application.ExecutablePath); Process.Start(psi); Application.Exit(); }
