I recently updated my iMac. I installed DevonThink Pro Office and ScanManager (for my ScanSnap scanner) on my Mac OS X Lion system. Most things are working fine. As before I installed ABBYY FineReader OCR. I confirm this last by looking at Install Add-ons dialog and see ABBYY line marked as Installed.
Every time I scan a document through my ScanSnap S1500M scanner, when it asks if I have finished or wish to continue and I click finish, I get the error messae OCR Engine Initialize Error! The dialog bears the Icon of ScanSnap manager not DevonThink. I thought OCR was done by DevonThink. I have my preferences set up to scan to a searchable PDF.
My old system was also running Lion but it was an upgrade to Lion, that is the applications and user files stayed in place as the Lion install changed the OS level. My current system has factory installed Lion and I had to install all the applications.
