How to execute a custom action before Pre-install?

[mli04]

Hi Team，

In the Prerequisites, I have set up the installation of the Postgres database, and I wish to dynamically create the database password during installation. To achieve this, I defined a DB_PASSWORD property and a custom action named NewDbPassword.

During the Wizard Dialogs Stage, I first invoked the NewDbPassword custom action to assign a dynamic password to the DB_PASSWORD property. However, the outcome did not meet my expectations; upon completion of the installation, the database password remained as the initial value of the DB_PASSWORD property. I have confirmed from the installation logs that the NewDbPassword custom action was indeed executed, and the DB_PASSWORD property was modified. I suspect that the issue lies in the timing of the NewDbPassword custom action execution, which might be taking place after the Postgres installation.

How can I configure the NewDbPassword custom action to execute prior to the Postgres installation? Any guidance would be appreciated.


Thanks,
Andrew

Hello Andrew,

In our latest versions we've added support to run an action before the prerequisite installation.

I've tested this with a sample project using v21.7.1 and everything works as expected.

Attached you can also find the two projects (prerequisite and main setup). Can you try this implementation with our latest version and see if it helps?

Hi Liviu,

I only have a license for version 19.0, and I am not sure if this license permits an upgrade to the latest version.

Thanks,
Andrew

Hello Andrew,

I have a look over our database and I found more licenses, from which some are with an active Maintenance Plan (e.g. you can download our latest version) and some with an inactive one.

In order to see for yourself, please go to "Customer Information" page:

https://www.advancedinstaller.com/custo ... ation.html

and enter your licnese key.

That should tell you whether the MP is active or not.

If the MP is active, then you can safely download our latest version to implement the solution my colleague Liviu has given you above.

Hope this helps!

Best regards,
Catalin
