Problem with Win32_Product - Upgrade method -1636 error code

P: 53
Hi all,

I am trying to do Software upgradation using Win32_Product -Upgrade method in C#.Net.

Here is the code.

using System;
using System.Management;
using System.Windows.Forms;

namespace WMISample
public class CallWMIMethod
public static void Main()
ManagementObject classInstance =
new ManagementObject("root\\CIMV2",
"Win32_Product.IdentifyingNumber='{AC76BA86-7AD7-1033-7B44-A00000000001}',Name='Adobe Reader 6.0.1',Version='006.000.001'",

// Obtain in-parameters for the method
ManagementBaseObject inParams =

// Add the input parameters.
inParams["PackageLocation"] = @"D:\softwares\upgradePatch.msi";

// Execute the method and obtain the return values.
ManagementBaseObject outParams =
classInstance.InvokeMethod("Upgrade", inParams, null);

// List outParams
Console.WriteLine("Out parameters:");
Console.WriteLine("ReturnValue: " + outParams["ReturnValue"]);
catch(ManagementException err)
MessageBox.Show("An error occurred while trying to execute the WMI method: " + err.Message);

When I run this code , I am getting 1636 error code, means the patch file is not correct.
But when I manually do the upgradation by double clicking on that msi file, upgradation is success. Then what is problem in this code. How to do it programatically. any suggessions plz........
