# AvailableVisualComponentsFlags

<Note>
  This topic applies to FRE for Windows.
</Note>

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

<Warning>
  Visual Components are currently only supported for Windows.
</Warning>

```
module AvailableVisualComponentsFlags
{
  const int AVC_ImageViewer    = 0x00000001;
  const int AVC_DocumentViewer = 0x00000002;
  const int AVC_TextEditor     = 0x00000004;
  const int AVC_TextValidator  = 0x00000008;
  const int AVC_Scanning       = 0x00000010;
  const int AVC_Training       = 0x00000020;
};
