I have some custom actions with a condition to run when a certain feature is installed.
&FeatureName=3
That works great with first time installs and major upgrades. However, I would also like the custom action to run during minor upgrades when that feature is being updated (newer files).
My initial thought was that the feature's action would be INSTALLSTATE_LOCAL for minor upgrades also. However, looking at the log it shows as re-install.
As such, the custom action does not run during minor upgrade. I then modified my condition to handle minor upgrades and maintenance repairs.
(&FeatureName=3) OR (!FeatureName=3 AND (REINSTALL="ALL" OR REINSTALL><"FeatureName"))
The above works great. I guess this forum post is less of question and more of a knowledge share in case others had similar scenario.
I was also wondering if anyone could shed some additional light on the IS_MINOR_UPGRADE property. I can't seem to find any documentation on the property in InstallShield help or in MSDN for Windows Installer.
Perhaps another option would be to use: (&FeatureName=3) OR (!FeatureName=3 AND IS_MINOR_UPGRADE)
