How to add new language to Tesseract OCR


I need to use ukrainian language in my progect (work with pdf bills).
So far Mircosoft OCR did not support urk language i using Tesseract OCR.
I tryed to use this guide: OCR languages
But i havent folder C:\Program Files (x86)\UiPath\Studio\tessdata
How can i install required language pack? Or how can i attach pack in other folder to Tesseract OCR?

I have this folder, but it’s wrong way.

But as you mentioned it’s somehow not working for you. You can try to work with MS OCR then. Here you have whole instruction for both. Maybe you missed something:

Microsoft OCR don’t support ukrainian language

What about Tesseract OCR compatibility? Have you checked if UiAtomation is correct against your Vision version?
