Hi List,
I am running an upgrade dialog and from the log I see that
MigrateFeatureStates correctly detects the feature which was previosly
installed. However, an upgrade will install not only that feature, but
also the rest of the features. The tutorial from tramontana.hu upgrades
based on user input, and what I want is to upgrade automatically only
the components installed.
I could create a custom action which logs if the feature is to be
installed or not when upgrading; to my surprise - MsiGetFeatureState
reports that all features are absent which means that it scans the
feature table. What is the API that tells me what feature is installed,
just like MigrateFeatureStates is reporting?
Best regards,
Calin
