Hi, " Why the version is 4.0." What do you mean by that? In logs it states that it's 3.04v. "Tesseract Open Source OCR Engine v3.04.01 with Leptonica". The problem might be the fact that 4th version is using lstm files whereas you have version 3.04 using box files instead. Try to check the version of installed Tesseract. Also note that I'm not the expert here ^.^
