Answer 1

I am also having the same specification as you.

Eclipse : 64bit

JDK 1.8 :64bit

OS :64bit

jar Tess4j :3.4.2 version

Check in your installed programs (Control Panel->Programs->Programs and Features) for

microsoft visual c++ 2015 redistributable x64 is avalable or not.

If not then download it from here and install it.

Then try your app running again. It worked for me
