I'm looking for a way to see if a driver is installed on a PC

Hi All,

I'm looking for a way to see if a driver is installed on a PC, it is for a USB to serial converter,
The problem is I want to check to see if there is a driver for it installed. At the moment I have the code
ServiceController[] scDevices = ServiceController.GetDevices();
foreach (ServiceController scTemp in scDevices)
lstDrivers.Items.Add(scTemp.ServiceType + "," + scTemp.ServiceName + "," + scTemp.DisplayName);

This appears to list several files that could be the driver I am looking for... (Microchip driver)

You can get more information about a driver using WMI and in particular the Win32_PnPSignedDriver class.

http://msdn.microsoft.com/en-us/library/windows/desktop/aa394354(v=vs.85).aspx

Here's some code to list the properties and their values for each driver. You'll need to add a reference to System.Management.dll to your project if it's not been added already:

using System;
using System.Management;

class Test
{
static void Main()
{

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPSignedDriver");

foreach (ManagementObject obj in searcher.Get())
{
foreach(PropertyData prop in obj.Properties)
{
Console.WriteLine("{0} : {1}", prop.Name, prop.Value);
}

Console.WriteLine("\nPress any key to view info for next driver");
Console.ReadKey();
Console.WriteLine();
}
}
}

Forgot I asked that(!) the problem is I have at least drivers it could be and I think the device uses a standard FTDI driver that I don't want to uninstall as I have several non-related bits O' hardware attached...

Seems similar to your previous problem in detecting whether a driver was installed or not (link below).

Are you saying this time that you're not in a position to install the driver, you just want to know whether it's installed already?
