ABBY creates for each job a separate folder in its temporary folder. I would suggest to clean the content and remove the subfolders. CCleaner in the version listed below did nothing.
Platform: Windows 7 Ultimate SP1 (x64, all updates)
Application: ABBY Fine Reader PE 11.0.113.164 (latest)
CCleaner: 5.22.5724 (x64)
%userprofile%\AppData\Local\Temp\FineReader11.00
Best regards,
