tesseract50.dll        Tesseract OCR 5.0          Apache License 2.0   https://github.com/tesseract-ocr/tesseract
leptonica-1.82.0.dll   Leptonica 1.82.0           BSD 2-Clause         http://www.leptonica.org/
  Both native DLLs are taken unmodified from the NuGet package "Tesseract" 5.2.0
  (https://www.nuget.org/packages/Tesseract/5.2.0, Apache-2.0, https://github.com/charlesw/tesseract).
  ITB Scan calls the Tesseract C API directly; the package's .NET wrapper is not used.

                       tessdata_fast models        Apache License 2.0   https://github.com/tesseract-ocr/tessdata_fast

The OCR engine needs the Microsoft Visual C++ 2015-2022 Redistributable (msvcp140.dll, vcruntime140.dll)
of the same bitness as ITB Scan. ITB Scan does not ship it; the OCR button says so when it is missing.
