I have a new Windows 7 (64 bit computer) and installed the
latest version of Tesseract 3.02 in c:/tesseract-ocr folder
and installed latest version of viet-ocr and copied
"deu-frak.traineddata" into viet-ocr tessdata folder.
When I try to ocr a page I get error message
OCR operation
"Attempted to read or write protected memory.
This is often an indication that other memory is corrupt."
Any help is appreciated

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I guess that you're using the .NET version, which still has the old Tesseract 3.01 engine (it will be updated as soon as the third-party library becomes available). Language data for 3.02 version is not backward compatible with 3.01. You should download using the built-in menu item to get the compatible language data.
FYI, the Java version has the new Tesseract 3.02 engine.
Let me know if that will solve the problem. Thanks.

Hi Quan,
I used this
http://sourceforge.net/projects/vietocr/files/vietocr/3.4.1/VietOCR-3.4.1.zip/download
Run ocr.bat
seems to be bug in open files of type ? there is no type suffix but that did not seem to stop it from working though.
It works after copying trained data file to c:/tesseract-ocr/tessdata
kind regards
Richard
