Running an installer from within C#

问题

I need to write code to download and run a program, e.g. notepad++ (npp.5.9.3.Installer.exe) this can be found on the web. I run it with the ProcessStartInfo class. However when I normally execute the notepad++ installer, it will show me a few steps before actually installing, like choose language, path etc.

Is there any way to programatically skip these steps, and install the software? I hope my question is clear. If it helps, I also attach the method that so far only starts the installer

        private int RunFile()
        {
            ProcessStartInfo psi = new ProcessStartInfo(GetFileFullPath());
            psi.WindowStyle = ProcessWindowStyle.Hidden;
            psi.CreateNoWindow = true;

            using (Process process = Process.Start(psi))
            {
                process.WaitForExit();
                if (process.HasExited)
                    return process.ExitCode;
            }
        }

Shall I pass some arguments for this to work? Thank you in advance.

Regards,

There are some installers which supports -s or -silent switches which means that when you install a software by passing -s switch to installer and it will silently install with default options. Try to find out whether your installer supports that or not

回答2:

Use npp.5.9.3.Installer.exe /S for unattended installation of notepad++, and %ProgramFiles%\Notepad++\uninstall.exe /S for uninstall.

you have to drive the installation emulating the user. It is possible send kind of command(message) to the other window from a C# application

have a look at the below

Interact with other desktop-applications in windows using C# winforms

A wellwritten installer have options for silent installs with no user interface. If the installer is an .msi file there are options that can be passed to msiexec to make a silent install.

For other install systems there are sometimes options to. Automating installations without user involvement is a common task for system administrators, so if you have questions on a specific installation package I would suggerst asking at ServerFault or AppDeploy. Unfortunately there are many bad installation programs out there that doesn't support silent install.

This will ONLY depend on the installer (npp.5.9.3.Installer.exe). You have to search if the installer provides options that can be used in command line, such as silentinstall.

EDIT: You can use the /S (capital S) option for Notepad++ to perform a silent install.
