Hi,
I have a installer package containing a custom action writing a text
file based on which Features are installed.
Il use the following condition in my vb script to check if a feature is
installed:
Session.FeatureRequestState("Feature")<>2 AND
(Session.FeatureRequestState("Feature")=3 or
Session.FeatureCurrentState("Feature")=3)
This works fine for new install, repair, and modify.
However, on a major upgrade, FeatureRequestState returns -1 and
FeatureCurrentState return 2. Il know that the features are actually
migrated, because the files related to each features are installed.
My MajorUpgrade element is defined like this:
<MajorUpgrade AllowSameVersionUpgrades="no" MigrateFeatures="yes"
DowngradeErrorMessage="Installed version is newer." />
How can I check if a feature has been migrated on a major upgrade in vb
script? Currently, my custom action is scheduled to run after
InstallFinalize.
Thank you.
Eric Prévost
