File exists but not found at runtime c#

Question

Hello there my code is like that:

if (result == System.Windows.Forms.DialogResult.Yes)
{
    try
    {
         Process myProcess = new Process();
         // Launch the usb backup creator
         myProcess.StartInfo.UseShellExecute = false;
         // get path of recovery drive
         myProcess.StartInfo.FileName = (Environment.SystemDirectory + "\\RecoveryDrive.exe"); ;
         myProcess.StartInfo.CreateNoWindow = true;
         myProcess.Start();
     }
     catch (Exception ex)
     {
         MessageBox.Show(ex.Message,ex.Source);
     }
}

The file exists in system32 directory, but the exception thrown says that the file does not exist?
Is that related to UAC privileges?

Answer 1

If you're experiencing the effects of the file system redirector because you're running as a 32-bit process (compiled for 32-bit or for AnyCPU with "Prefer 32-bit") then you probably want to use the following code:

Path.Combine(Environment.GetFolderPath(SpecialFolder.Windows),
             "sysnative",
             "RecoveryDrive.exe");

to get the correct path. You can determine if this is the case by checking the Environment.Is64BitProcess property.
