I have one strange problem with installer package. When i try to change the installed package using Setup.exe or launching app.msi manually; it directly starts installation of application without even showing Maintenance Mode window to user.
I have verified that after installation of application it has made proper entry in registry @[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall].
This use to work properly before and suddenly i'm getting this issue, even though there is no changes done while authoring package.
MaintenanceWelcome action condition in InstallUISequence
