Answer 1

I have just completed a project with tesseract engine 3. i think, there is a bug in the engine, that need to be rectified. What i Did to remove "AccessViolationError" is, add "\tessdata" to the real tessdata directory string. I don't know why, but the engine seems to be truncating the innermost directory in the Tessdata path.

Just made Full OCR package (Dlls+Tessdata(english)) that works with .net framework 4.

Answer 2

Seems your problem relates to stability issue mentioned here. On the official site there is a recommendation to use previous stable release 2.4.1. You can install it from nuget.org via the package manager command: Install-Package Tesseract -Version 2.4.1

Answer 3

It appeared to be the contents of the tessdata folder that was causing the problem. Obtained the tessdata folder from the first link and all is now working.

Answer 4

If somebody has the same problem and advice with trailing slash doesn't work, try... TWO ending slashes! Seriosly. It works for me.

if (processor.Init(@".\tessdata\\", "eng", (int)eOcrEngineMode.OEM_DEFAULT))
