I would like to show a message box (like SdShowMsg in installscript) during execution of custom action (executes another .exe file) in Basic MSI project. How can it be done?

Thanks.

Maybe you can try the SdShowMsg Installscript function (via an Installscript custom action):

That's exactly what I don't want to do. It means that user will need the installscript engine on the target machine. I prefer to use only Windows Installer technology.

I am not aware of a built-in MSI feature that will accomplish this. There are basic dialogs embedded in the msiexec.exe engine, but I believe those are only shown if there is no GUI in the MSI being installed. I guess you have to write yourself a win32 modeless dialog and show it from either a dll or exe custom action... Alternatively there is the billboard feature of MSI that can possibly be used to work around the problem, but as I understand this feature is buggy.

You could add your custom actions progress to the general progress bar, as described in the MSI docs. Or you could add a non-modal dialog to your setup, similar to the initialization dialog. Or you could display the dialog from your custom action itself, with proper conditions to make sure it isn't displayed in silent mode.

I've used the Basic Script MsgBox function and it works just fine. That will only work if you have a very simple Custom Action that you can code in Basic Script.

Hi Rick, that's very interesting, would you mind sharing this code with the rest of us? It might be a good reference for someone in the future.
