Remote MSI Installation using VB.net

I have a vb.net app that searches for specific computers on the network based on criteria from a database and applies modifications if needed.  In certain cases it needs to install an msi.  I experimented with WMIC using:

/node:RemoteComputerName product call install true,"" , "C:\Test_Install.msi"

This worked great and allowed me to install the msi using my domain admin credentials regardless if a user is logged into the remote computer or not.  However, when trying to apply the attached vb.net solution, it will only install if the computer is logged in and only if I pass the credentials of the user that is currently logged in. The error log on the remote computer will show the failure as an MSIINSTALLER issue related to user rights.

I am not opposed to using something other than WMI but absolutely want to automatically initiate the remote install from my vb.net application.  I do not want to visit any solution that requires Group Policy deployment or SCCM.

This solution is applied to workstations running XP and WIN 7, both 32 and 64 bit.
 
Imports System.Management

Public Class Form1

    Private Sub subWMInstall()

        Dim strComputer As String = "RemoteComputerName"
        Dim ConnectionOptions As New System.Management.ConnectionOptions
        ConnectionOptions.Username = Trim("DomainAdminUserName") '(strComputer & "\LocalAdminUserName") for local user account
        ConnectionOptions.Password = Trim("DomainAdminUserPassword")

        Dim ManagementScope As New System.Management.ManagementScope("\\" & strComputer & "\root\cimv2", ConnectionOptions)
        Dim ManagementPath As New System.Management.ManagementPath("Win32_Process")
        Dim ManagementOptions As New System.Management.ObjectGetOptions
        Dim ManagementClass As New System.Management.ManagementClass(ManagementScope, ManagementPath, ManagementOptions)
        Dim OutputParameters As System.Management.ManagementBaseObject
        Dim InputParameters As System.Management.ManagementBaseObject

        Try

            ManagementScope.Connect()
            InputParameters = ManagementClass.GetMethodParameters("Create")
            InputParameters("CommandLine") = "msiexec /package C:\Test_Install.msi"
            OutputParameters = ManagementClass.InvokeMethod("Create", InputParameters, Nothing)

        Catch ex As Exception
            MsgBox("There was an error connecting to the remote computer." & vbNewLine & ex.Message)
        End Try

    End Sub
    
End Class

Try using the computer account for installation.

I do not know how to specify the Machine or System account in this context.  Do you have an example or link to an example?

I cannot write the code myself as it has been many years that I wrote anything apart from scripts!

Anyway this may help you

The details in that link might eventually lead to fixing the code above but would take a considerable amount of time to absorb, modify, and implement.  Alternatively,  I found a very simple working example in a VBS script that was easily modified to work in VB.net as long as the application is run with a domain admin account:
Private Sub subWMIInstall(strComputer As String)

        Dim errReturn As String

        Try
            Dim objWMIService As Object = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
            Dim objSoftware As Object = objWMIService.Get("Win32_Product")
            errReturn = objSoftware.Install("c:\Test_Install.msi", , True)

        Catch
            MsgBox("FAILED: " & errReturn)

        End Try


    End Sub

Was looking for a simple fix to the provided code or an alternate solution which i found elsewhere but decided to share.
