How can i solove tesseract OCR error?

hello, I want to read text from PDF file with Tessereact OCR. Tesseract OCR’s language setting is eng. Here is error log.
I didn’t install tesseract. Does this affect an error?

안녕하세요, tesseract OCR로 PDF를 읽다가 다음과 같은 오류가 났습니다. 엔진 언어설정은 영어입니다.
밑에 오류로그를 첨부하겠습니다. 그리고 tesseract를 설치하지 않아서 생기는 건 아니겠죠?

this is Runtime execution error message.

I’m appreciate your kindness! I read some answers that you sent me. Now it is working with MS OCR instead of Tesseract OCR.
