Thanks for this detailed explanation. Sanjay, you'll have to create a custom action that shows your dialog and then run this custom action from the MSI. The dialog itself is within the custom action DLL. So when you create the custom action from the C++ template, just add a Windows form dialog there. This is not a dialog from the MSI file.
