SFX Install Button

Question

I am working on a program that needs to extract a WinRar SFX automatically. Is there anyway I can programmatically click a install button once the exe is started with a Process? Here is the code that I have so far.

public bool Extract()
    {
        try
        {
            Process process = new Process();
            process.StartInfo.WorkingDirectory = FilePath;
            process.StartInfo.FileName = FilePath + fileName;

            process.Start();

            process.WaitForExit();
        }
        catch (Exception)
        {
            return false;
        }

        return true;
    }

Answer 1

You could make the sfx silent with winrar.
