For my application I have an .msi developed with WiX. For the update scenario I want to do the following:
- if the installed version is never than the update version display an error 
- if the installed version is older than the update version show a button with text - Update
- if the installed version is the same as the update version show a button with text - Repair
I have found how to define custom UI dialogs, but if I create a dialog with all these controls (Error label, Update/Repair buttons) how can I display just the appropriate one according to the situation.
