I'm having a little problem with some drivers on my different machines using system images.  Some of the newer HPs won't install thing like audio or the hot keys because they don't show up in device manager with errors.  I want a single WIM image for all of our production machines.  To make it work I came up with a VBS that checks the system WMI then kicks off the installer for the appropriate hardware as a post install task.  It works nice - except stinking windows is pulling up the box that says it can't verify the app developer and I need to click to install the software.  Any ideas on how to suppress this pop up?  I've tried running it as a windows script and a calling it with a bat but it's popping up and causing my image to require user intervention.  

Here is the script I'm calling these with:

On error resume next

Dim strComputer, objWMIService, strmodel, colmodel, objitem

    strComputer = "."

    Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

    Set colmodel = objWMIService.ExecQuery("SELECT * FROM Win32_ComputerSystem")     

    set objShell=wscript.createObject("wscript.shell")

'Install Model Specfic software / Drivers

For Each objitem in colmodel

        'wscript.echo objitem.model

            Select Case trim(objitem.model)

                Case "HP ProBook 640 G1"

                   ' wscript.echo "Machine type HP Probook 640 G1"

                    ObjShell.Run(“\\server\share\Drivers\windows_7_x64\HPProBook640G1\Audio\setup.exe -s"),1,true

                   wscript.quit 

                     Case Else

                      ' Wscript.echo "Computer Type Unknown"

            End Select

Next

Thanks for any thoughts!
