Abbyy OCR is not visible in screen scraping

I already installed installed ABBYY FlexiCapture Standalone in my machine with trial key.

I also put the UiPath.FlexiCapture.Activities inside activities folder.

The Abby activities can be seen in activities panel.

But I still can’t see the ABBYY OCR in screen scraping. (Screenshot below)

Has anyone has an idea on how ABBYY OCR will be in screen scraping?
