After installing Tesseract add-on, TextRecognize in Mathematica crashes

I have installed and used Tesseract (ver 3.02) without any problem before I installed Mathematica on my Windows 8.1 (64-bit). When I tried TextRecognize, I got the following message:

LinkObject::linkd: Unable to communicate with closed link LinkObject["C:\Program Files\Wolfram Research\Mathematica\9.0\SystemFiles\Converters\Binaries\Windows-x86-64\Tesseract.exe",453,7].

I rebooted my PC and started Mathematica, and it crashed again. I don't know if my original Tesseract version is conflicting with the Mathematica's bundled version. Any suggestion to solve the problem?

I had the same problem as you (I had Tesseract 3.0.2 installed as well).

I had to uninstall it (didn't help by itself) and then remove the installation directory ("C:\Program Files (x86)\Tesseract...") and finally search the Windows registry (regedit.exe) for any leftover 'tesseract' entries (I zapped them all) and then reboot my machine.

We're working on overhauling this OCR functionality for the Wolfram Language, so I expect that a future version will not have this software compatibility conflict.

Let me know if this helps you (or not)!

I haven't seen this myself, but I would suggest resetting Mathematica's preferences to the default configuration and then reinstalling Tesseract.

If you still see this problem, you may want to contact Wolfram Technical Support.
