find a Particular product present in a remote system or not

Question

Trying to find the product is installed in remote pC or not, it takes long time to execute, is there any ways we can achieve this faster.

//usage: //uninstall4("hostname", "productname", "{AC9C1263-2BA8-4863-BE18-01232375CE42}", "10.0.0.69");

    public void uninstall4(string targetServer, string product,string guid , string version)
    {
        //Connect to Server
        System.Management.ConnectionOptions connoptions = new System.Management.ConnectionOptions();
        connoptions.Impersonation = System.Management.ImpersonationLevel.Impersonate;
        connoptions.Timeout = new TimeSpan(0, 0, 10); // 10 seconds
        System.Management.ManagementScope scope = new System.Management.ManagementScope(@"\\" + targetServer + @"\root\cimv2", connoptions);
        scope.Connect();

        string q = "select * from Win32_Product where name = '" + product + "' and IdentifyingNumber='"+guid+"' and version = '"+version+"'";

        System.Management.SelectQuery query = new System.Management.SelectQuery(q);

        System.Management.EnumerationOptions options = new System.Management.EnumerationOptions();
        options.EnumerateDeep = false;
        options.ReturnImmediately = false;
        options.DirectRead = true;

        using (System.Management.ManagementObjectSearcher searcher
            = new System.Management.ManagementObjectSearcher(scope, query, options))
        {
            using (System.Management.ManagementObjectCollection moc = searcher.Get())
            {
                if(moc == null || moc.Count == 0)
                {
                    throw new Exception("product Not Found");
                }

            }
        }

    }

Nope. The provider for the Win32_Product class has to build the information dynamically when you query it, and it's always, always slow.
