With DoAction custom actions in the UI sequence, there doesnt seem to be any MSI specific way so just use MessageBox(). To get the parent window for the message box, so that it appears on top of your dialog, see http://www.mail-archive.com/wix-users@lists.sourceforge.net/msg00415.htm l

And in case of error I want to show error message, currently I'm using MsiProcessMessage and session.Message methods, which are working fine if CA performed in install execute sequence. But message is not shown if I'm trying to execute these actions in UI sequence through DoAction publish event. I have read in msi documentation, that it is be design, so my question what is the best approach to show error message box from such situation?
