Hello and welcome to Advanced Installer forums,
In order to achieve that you can go in the
Install Parameters page and
Create or edit a property(e.g. MY_PROP).
Then you can go in the
Registry page, create your
registry value and in the
Data field your can have something like
[MY_PROP].
So, when you are running your package from the command line you can use something like:
MSIEXEC.exe /i SomeMSI.MSI MY_PROP=”BLAHBLAH ”
Please let us know if that helped.
Best regards,
Dan
