Had the same kind of issue here…version 3.5.1 and working last week normal and now this morning this issue… also deleted the SDK folder and OCR working again.
Feels a bit strange to delete a folder this way. How is it possible this issue all of a sudden is there ?
@MMW you are a lifesaver. @BLUEFROG FYI–I had exact same problem.
deleting ~/Library/Application Support/ABBYY/SDK did the trick. I followed this thread from the very top, trying each suggestion in order–doh! After trying all the recommendations in order to include de-activating my license and so on, I finally got down to the SDK folder recommendation. Deleting that worked. OCR functioning normal again.
I licensed the software about a week ago, after trialing it for three days. I’ve been testing the OCR feature extensively with some scanned PDF files in batches since then.
The procedure suggested by @aedwards successfully resolved the initial issue.
Later on after resuming the scanning, the process got stuck ‘Adding Document’ for more than an hour and I had start all over from the first unprocessed file.
This is still an issue. I get about 20 large pdfs OCR’d then the error reappears and it quits OCR’ing… Even after the workaround, the license error still returns in 3.6.3
