Install a .inf driver programmatically using C# .Net

Here is the example to Install a .inf driver programmatically using C# .Net.

Installation of .inf driver using c# is easy. Please check the following code for that.

private static void driverInstall(string driverPath)
       {

           try
           {
               var process = new Process();
               process.StartInfo.UseShellExecute = false;
               process.StartInfo.CreateNoWindow = true;
               process.StartInfo.RedirectStandardOutput = true;
               process.StartInfo.RedirectStandardError = true;
               process.StartInfo.FileName = "C:\\Windows\\System32\\cmd.exe";
               string a = @"" + driverPath + "";
               process.StartInfo.Arguments = "/c C:\\Windows\\Sysnative\\PnPutil.exe -a \"" + driverPath + "\""; // where driverPath is path of .inf file
               process.Start();
               process.WaitForExit();
               process.Dispose();
               Console.WriteLine(@"Driver has been installed");
           }
           catch (Exception ex)
           {
               Console.WriteLine(ex.Message);
           }
       }

Note: Please note that here I used Windows\Sysnative folder instead of Windows\system32 for PnPUtil.exe path. c:\windows\system32\pnputil.exe path is ok for 32bit system. But when you are working with a 64bit system, you must change path to c:\windows\sysnative\pnputil.exe.

You may face the following error during .inf driver installation using c#.

Error: pnputil.exe is not recognized as an internal or external command, operable program or batch file.

Solution:

If you are using path “c:\windows\system32\PnPUtil.exe” for cmd arguments then you may face the error like “pnputil.exe is not recognized as an internal or external command, operable program or batch file”.¬†The Solution is simple replace “c:\windows\system32\PnPUtil.exe” with¬† “c:\windows\sysnative\pnputil.exe” as per my above example. for more details you can visit: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019L4VSAU&l=en-IN
