Upgrading Packages in Group Policy

• When upgrading a software package from another group policy, the new group policy must be ahead of the upgraded group policy in the link order (i.e. the new policy must have a higher precedence than the old policy).
• MSI Custom Actions do not support the WScript object model (see the example below).

Set WShell = WScript.CreateObject("WScript.Shell")

instead of

Set WShell = CreateObject("WScript.Shell")
