How to pass parameters to a Powershell script file custom action

Question

I have a Powershell Deferred Custom Action that I want to change from In-line Script to Script From File. The problem is that the Advanced Installer GUI no longer has a "Parameters" field to let me pass MSI installer public properties into the script:

Parameters field for Inline:

No Parameters field for File:

How can I pass values into a Powershell Script File, similar to how I could for an in-line script?

To get a property simply include a line with the following syntax in your script:

$propValue = AI_GetMsiProperty YOUR_PROP

Where YOUR_PROP is the property name.

To set a property simply include a line with the following syntax in your script:

AI_SetMsiProperty YOUR_PROP <VALUE>

Where YOUR_PROP is the property and is the value assigned to it.

For details, please check the PowerShell CA article.
