I have a problem with my project . I have recently upgraded from Express X to Express 11. I have a project in Express X that calls an uninstall custom action at “Before System Changes” location in the project.

On Express X this custom action gets called when the install is being modified, or removed (modify mode, remove mode). This is the desired behavior, however, in Express 11 it is only getting called during the remove mode and not at all during modify mode. Has this changed between product versions? Shouldn’t a custom action at this location be called in modify and remove modes? If not, how can I add a custom action before system changed in modify mode?
