# Creation Methods of the Engine Object

The [Engine](/fine-reader/engine/api-reference/engine-object-iengine-interface) object exposes the methods which create other ABBYY FineReader Engine objects.

<Note>
  If you work with programming languages which do not have garbage collection (for example, C++), you must either use smart pointer classes (see the [samples](/fine-reader/engine/guided-tour/samples) in C++ and (COM)) or release objects that were created by creation methods when they are no longer needed. Prior to the Engine deinitialization, you must release all created objects. Otherwise, the [DeinitializeEngine](/fine-reader/engine/api-reference/functions/deinitializeengine-function) function returns E\_FAIL.
