03-20-2008, 10:42 jerrydykstra Joined on 01-09-2008 Posts 8 Remoting server OCR initialization failing I am working on an application that sends an image over .net remoting to save the image and OCR it.  I have it working fine in my prototype, but when I ported the code to our production remoting service code, I keep getting the "OCR engine initialization error, or there is no appropriate license" exception.  I have looked through the previous posts on this subject and followed the suggestions in them.  I am single threading through the OCR process, as I realize that it is not thread safe.  I have checked the production remoting service (which I am still running locally) project against the prototype project and I can't find any differences.  I have a valid OCR license.  Both virtual directories are set up with identical options.  I have tried setting the EnginePath but that doesn't seem to make a difference.  I downloaded the OCR web sample and it works fine after I set my OCR license key.  Is there any way to track down more specifically why the initialization is failing?  At this point I'm not sure if I have a licensing problem or a setup problem.    Report

If both projects are running on the same PC, OCR works in one of them but not the other, and you specify the EnginePath to point to the exact same folder in both programs, this most likely indicates the project that fails does not have sufficient access to see the OCR engine files. Is this the case? Adam Boulad LEADTOOLS Technical Support    Report

Does creating a virtual directory solve the problem in the server with the IIS service? If you want me to try and check the problem here, is it possible to create a small project that only attempts to initialize the OCR engine similar to yours, and send me this small project along with detailed instructions on how to set it up like your own project?
