This is a simple vbscript.  You will have to change the variables for uninstallPath and installPath.  Change these to the commands to remove the application (uninstall program or msiexec command to remove the app) and to install the new (make sure it's got the correct switches to make the install silent.)  My sample uninstalls TN3270 and installs a program on \\someserver\someshare

'~~~~~~START~~~~~~~~
Option Explicit
Dim wShell, uninstallPath, installPath

Set wShell = CreateObject("WScript.Shell")

uninstallPath = "C:\WINDOWS\IsUninst.exe -f"C:\Program Files\SDI\TN3270 Plus\Uninst.isu"
installPath = "\\SomeServer\Someshare\Setup.exe /s"

wShell.Run uninstallPath,,True
wShell.Run installPath,,True

WScript.Echo "Upgrade complete"
'~~~~~~~~~END~~~~~~~~~~~~~

Just out of curiosity what is the software you are pulling/pushing?  It might be easier to mange with group policy.

Does the installer package come with an MSI installer file? (Usually in the root of the CD or install folder)

You might consider removing the old software via script as mcsween mentioned and installing the new package via group policy.  This way the next time a package comes out you can delete the old policy (there is a setting that will remove the software if the policy is removed) and push out the new package.

I agree with SamuraiCrow, if you have a msi then I would deploy the new one via GPO.

Alternatly:

Create a GPO to deploy the OLD version (the one that's currently installed)
Wait a week or so untill all clients have installed the old package (should install right over current install)
Add the New package to the GPO and on the Upgrades tab click Add, and select the OLD package
Check the box that says "Uninstall the existing package, then install the upgrade package"

You may want to test this method on a test machine before allowing it to propogate to all of AD.
