[Basic Msi Project] Information type messages cannot be written via c# custom action on next button click.

Problem statement:

On next button, C# custom action is integrated with a dialog. Via this c# custom action, we want to write information(verbose) messages. But this is not working.

To confirm the same, we have created POC and attached it here.

POC Content:

- InstallShield Project type: Basic Msi Project, Custom action: C# class library (.net framework 4.7.1)

- InstallWelcome > Next button click, invokes custom action to write information message. (which is not working or we can say message is not logged into log file.)

- LicenseAggrement > Next button, invokes custom action to write Error message. (which is working and we can see the same message into log file).

- Set "/L*vx install.log" in MEDIA > Releases > configuration > Setup.exe tab > MSI Command-Line Arguments.

Let us know what can be possible approach to solve the problem.

In order to be called, the custom action must be scheduled in the sequences. For this example, open the Custom Actions view and create an immediate-mode  custom action called callLoggingTest that calls the LoggingTestInstallScript function, and schedule it to run after LaunchConditions.  Using next button in Setup Dialogs, it wont write to msi log.
