In IS2009 how are IS_MAJOR_UPGRADE and IS_MINOR_UPGRADE set? In my custom action I would like to execute an installscript function only when:
It is a major upgrade It is a minor upgrade
I just can find documentation on the different methods for performing different scenarios for executing custom actions, screens, controls, and other tasks.
Different scenarios I can think of:
Patching Minor Upgrade Major Upgrade Installed Uninstalling Reinstalling
I would truly appreciate if someone can point me to the right documentation.
To detect a major upgrade, use the action property in the major-upgrade item (or Upgrade table), by default ISACTIONPROP1; for a minor upgrade, use the same condition as SetupResume.
