Uninstallation dialog doesnt appear when uninstallating from Control Panel

When the setup is run by double-clicking then the setup dialog appears as expected. When I want to un-install by double-clicking the setup, then the setup dialog appears with options to Change, Repair and Remove. However, when I try to uninstall through Control Panel, the dialog doesnt appear and uninstallation kicks off. Same thing happens when I right click on the setup file and choose Uninstall. How do I make the dialog appear every time when an uninstall is invoked?

Nithin when you try to uninstall through Control Panel, the dialog doesn't appear and uninstallation starts with Windows Installer progress bar dialog.
Yes, that's the default behavior of the Add/Remove Programs. It always uninstalls MSI packages in basic mode after prompting.
The only place you can author UI during an uninstall is a "change" or "maintenance" UI. But there are some tricks to achieve it.
1> Bootstrapper which calls your MSI with the desired UILevel rather than allowing ARP call your MSI directly.
2> Set ARPNOREMOVE property to force a user to use maintenance mode. But this would actually remove the option to Uninstall your product from both Control Panel and its Maintenance Dialog box.
so redefine Maintenance Dialog while enabling the Remove button forcefully using Condition element can do your work.
