After reading the Charlotte Gonella article about “active setup” techniques (link), I automated this technique in Wise Package Studio...

In Wise Package Studio, select "Installation Expert" mode. In the "Registry" tab, create a new key under HKEY_LOCAL_MACHINE :

Software/Microsoft/Active Setup/Installed Components/[ProductCode]

We are inserting automatically by this way the unique value of the package UID

Under that key, Add a value named "StubPath" containing this string :

msiexec.exe /fu [ProductCode] /q

The "Active Setup" call for your application, is done automatically by the [ProductCode] property.

Now you can use this skeleton as a model for future packages based on the "Active Setup" technique.

That’s all!!!
