Feature

one feature in every MSI file. And a feature can have a parent and child
features also. Feature table contains the list of features that are present in
a specific MSI file. The following are the columns of Feature table:
For
example suppose there are two features Feature

msi file. Suppose ‘Feature 1’ feature is
child feature of ‘Feature 2’ feature.
