I first rated OmniPage 17 Known Not to Work because startup attempts produced an error message. When I overcame that problem, startup attempts produced only a splash screen, and I kept Known Not to Work.
I still haven't got OmniPage to run via its normal user interface, but have performed file conversions using both the Batch Manager and PDF Create - each of which is part of an OmniPage installation. Although I'm uncomfortable giving a Bronze rating to an application that only appears to produce a splash screen, I must admit that there's a lot of functionality available.
By keeping a Known Not to Work rating, I'd discourage installations, and others would miss out on that functionality, so I raised my rating to Bronze, knowing that it's a questionable decision.
