It is not really related to your question, but I had a question about popup message box from custom action and I got an answer from Bob Arnson: Set a property in the CA and use that property as the condition in a SpawnDialog control event to show a message box. Never show UI from a CA; there's no way to get the same UI level information that MSI uses to determine whether UI should be shown. So probably try to change not to popup message box from CA, but SpawnDialog (new dialog?) from installer UI and maybe after closing it, you will have a correct focus.

You have several choices. First, you can rearrange things with one required field per dialog so that its always clear which field needs a value. Second, you can keep all the fields on the same dialog, but not enable the Next button until all the requirements are met (control properties are not empty) and use a text control (initially showing no text) that holds the error message. An additional text control can be placed next to the offending fields so that an asterisk or other marker can be displayed next to fields needing attention. Your "DoAction" on the next button will probably need to work around the fact that Windows Installer doesn't recognize property changes correctly inside a DoAction attached to a button.
