# AvailableEngineModulesFlags

The AEM\_ prefixed flags are used to denote [the possible ABBYY FineReader Engine modules](/fine-reader/engine/licensing/modules) whose availability depends on the license. The [ILicense::AvailableEngineModules](/fine-reader/engine/api-reference/license-related-objects/license#availableenginemodules) property returns a bitwise OR combination of zero or more of these flags values, where each set bit indicates that the corresponding ABBYY FineReader Engine module is available in the license.

```
