“File not found” error launching system32\winsat.exe using Process.Start()

Question

I\'m trying to run the Windows System Assessment Tool (winsat.exe) using the following code:

System.Diagnostics.Process WinSPro =
    new System.Diagnostics.         


        

Answer 1

Based on Simon MᶜKenzie's answer, and the link he provided (thanks to soyuz for his comment) I wrote method that should work in either cases (to just copy/paste the code):

public static string GetSystem32DirectoryPath()
{
    string winDir = Environment.GetFolderPath(Environment.SpecialFolder.Windows);
    string system32Directory = Path.Combine(winDir, "system32");
    if (Environment.Is64BitOperatingSystem && !Environment.Is64BitProcess)
    {
        // For 32-bit processes on 64-bit systems, %windir%\system32 folder
        // can only be accessed by specifying %windir%\sysnative folder.
        system32Directory = Path.Combine(winDir, "sysnative");
    }
    return system32Directory;
}

and code to launch the process:

var pi = new ProcessStartInfo
{
    FileName = Path.Combine(GetSystem32DirectoryPath(), "winsat.exe"),
    CreateNoWindow = true,
    UseShellExecute = false
};
Process.Start(pi);
