MSI supports dialogs in the uninstallation but doesn't require it, but Add/Remove Programs (whatever it may be called in the different versions of the OS) calls MSI in a mode that disallows it (when the "Remove" or its equivalent is selected). You shouldn't use a custom action that produces a modal dialog to override this behavior or you will stall tools that remove products in an unattended fashion.
You can make the shell (which owns the Add/Remove Programs applet) not show the Remove button (but instead allow your dialogs to show UI) by adding the ARPNOREMOVE property (usually set to 1) to your product (make sure the ARPNOMODIFY is not set by checking your MSI in Orca). This causes the shell to show a "Change/Remove"-type button for the "Modify" case. Then you should be able to author dialogs that allow you to ask the user when they click your maintenance dialog's "remove" button. For some reason WixUI_Minimal and WixUI_InstallDir both set ARPNOMODIFY, so you would need to use one of the other UI flows if you are using the WiX-supplied sequences. -----Original Message----- From: Sebastian Brand (Instyler Software) [mailto:wix+us...@instyler.com] Sent: Monday, September 14, 2009 12:55 AM To: 'General discussion for Windows Installer XML toolset.'

Since MSI does not support dialogs in the uninstallation of a product, you'll have to create a Custom Action for asking the user.
