Hi Michael,
I just tried the Windows OCR engine on one of the sample image files with text.
It did not have any problems.
This will obviously not mean that the action works fine :).
So it is hard to say why it gets stuck on this action for your particular file.
I'm sure your file would be a sensitive one and you won't be able to share it. But if you are then I can give it a try.
Also check for any errors log messages. Perhaps raising a ticket with support could be of any help.
