I am writing a managed custom action. I am using the DTF Framework from Windows Installer Xml to wrap the managed dll into a usable CA dll. The CA does what it is supposed to, but I am still having trouble with error handling:
Dim record As New Record(1)
' Field 0 intentionally left blank
' Field 1 contains error number
record(1) = 27533
session.Message(InstallMessage.Error, record)
The above code produces the following text shown in the MSI log:
MSI (c) (C4 ! C6) [13:15:08:749]: Product: TestMSI -- Error 27533. The case-sensitive passwords do not match.
The error number refers to the code contained in the Error table within the MSI. The Message shown above is correct.
My problem is: Why does Windows Installer NOT create a dialog notifying the user about the error?
