Anyone know how to upgrade the current version of Tesseract to latest version shown in Github?

I need some guidance on that.

The safest recommendation is to upgrade your version of Blue Prism and stay with the version of tesseract that's included with the installation. What version of Blue Prism are you using? Blue Prism version 6.5 and higher are installed with Tesseract version 4.0.0, and earlier versions used tesseract 3.05.

The latest version of tesseract is 4.1.1 - if you really wanted to use 4.1.1 instead of 4.0.0, it looks like you could, but make sure you test.
Steps:
-Build a static executable (self-contained) tesseract.exe compatible with Windows.
Instructions here: https://tesseract-ocr.github.io/tessdoc/Compiling.html#windows
-Replace the existing tesseract.exe & accompanying tessdata file, default location is here: C:\Program Files\Blue Prism Limited\Blue Prism Automate\Tesseract
If you have any language data files, make sure those are compatible with your version of tesseract and update them if necessary as well.
-Check Tesseract engine setting under System settings on the application server.

Hi Patrick,
Thanks on that, I am using 6.4. That where I need tesseract 4.0.
