# Licenses Object (ILicenses Interface)

This object is a collection of available (activated) licenses. The collection is accessible via the [Engine](/fine-reader/engine/api-reference/engine-object-iengine-interface) object.

* The indexing of ABBYY FineReader Engine collections starts with 0.
* The foreach statement in C# (for each in Visual Basic .NET) can be used to manipulate the collection.
