After reading the Charlotte Gonella article about Ã¢Â€Âœactive setupÃ¢Â€Â 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.
