I'm using WMI in C# to get all the installed softwares but it doesn't show all the softwares only Microsoft ones

Question

  public ManagementScope GetScope()
    {
        try
        {
            //string classScope="winmgmts:" + "{impersonationLevel=impersonate}!\\" + strComputer + "\\root\\cimv2";
            string serverString = @"root\cimv2";

            ManagementScope scope = new ManagementScope(serverString);


                ConnectionOptions options = new ConnectionOptions
                {
                    Impersonation = ImpersonationLevel.Impersonate,
                    Authentication = AuthenticationLevel.Connect,
                    EnablePrivileges = true
                };
                scope.Options = options; 

            return scope; 
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            throw;
        }
    }

    public void InvokeMethodsFunctions1()
    {
        ManagementScope mScope = GetScope();

        mScope.Connect();

        if (mScope.IsConnected)
        {
            ManagementClass processClass =
                new ManagementClass(mScope.Path);
            ManagementObjectSearcher mos = new ManagementObjectSearcher(mScope, new ObjectQuery("SELECT * FROM Win32_Product"));
            //get collection of WMI objects
            ManagementObjectCollection queryCollection = mos.Get();

            using (System.IO.StreamWriter file = new System.IO.StreamWriter(@"Result.txt"))
            {
                textBox1.Text = "";
                //enumerate the collection.
                foreach (ManagementObject m in queryCollection)
                {
                    // access properties of the WMI object
                    string line = " " + m["Name"] + " , InstallDate : " + m["InstallDate"] + " LocalPackage : " + m["LocalPackage"];
                    Console.WriteLine(line);
                    file.WriteLine(line);
                    textBox1.Text += line + "\n";
                }
            }

       }

    }

There is nothing wrong , the Win32_Product WMI class only list the products installed by the Windows Installer (MSI).

Yes this is my problem, is there a way i can list also products that not installed by (MSI) – Khaleel Hmoz Oct 31 '13 at 07:50
@KhaleelHmoz: Yes, from the registry. See this question: [Get installed applications in a system](http://stackoverflow.com/q/908850/113116). – Helen Nov 01 '13 at 08:42
I'm Having a Problem with the Registry values i need to search about, I'm trying to Monitor Some software if they installed , but lately these software had made the displayname values localized and im trying to find values not localized in the registry, there is no such values. so i tried to get the other way which is WMI hoping that the values I get will be in English. the first problem now is i need to get all installed softwares even not from MSI... : ( – Khaleel Hmoz Nov 03 '13 at 09:28

I just tested the following, simplified version of your code and I see everything installed on my pc, even services I wrote and installed myself:

var products = new ManagementObjectSearcher(new ObjectQuery("SELECT * FROM Win32_Product"));
var result = products.Get();

foreach (var product in result)
{
    Console.WriteLine(product.GetPropertyValue("Name").ToString());
}

Console.ReadLine();

It looks like you are narrowing your query by scope, which is possibly why you aren't seeing everything, try the above and see if you have more luck.

I'm trying to get names of software not installed by MSI, thats why there is some softwares dosn't appear, because they installed from their own installer — Khaleel Hmoz, Nov 03 '13 at 09:33

I'm using WMI in C# to get all the installed softwares but it doesn't show all the softwares only Microsoft ones
