Removal of prior versions before installing 7.0

Question

We have about 225 employees, most of whom have Acrobat Approval 5.0 still installed on their systems. We are switching to the server-based Livecycle Reader Extensions and so we need to remove Approval from all systems before we install Reader 7.0. Is there a way to build this into the Acrobat Reader 7.0 installation file using InstallShield Tuner 7.0 so that we don't have to manually go to every computer and uninstall prior versions of Acrobat products?

Answer 1

I think I replied to the same message on appdeploy.com,
The command >
C:\WINDOWS\ISUNINST.EXE -y -a -f"C:\Program Files\Common Files\Adobe\Acrobat 5.0\NT\Uninst.isu" -c"C:\Program Files\Common Files\Adobe\Acrobat 5.0\NT\Uninst.dll"
Will uninstall Acrobat 5.
A script that does this might look like this,
Set oShell = CreateObject("WScript.Shell")
oShell.Run("C:\WINDOWS\ISUNINST.EXE -y -a -f"C:\Program Files\Common Files\Adobe\Acrobat 5.0\NT\Uninst.isu" -c"C:\Program Files\Common Files\Adobe\Acrobat 5.0\NT\Uninst.dll""),1,TRUE
That will deinstall Acrobat 5 :).
