I tried to add -Djna.library.path to my libtessract305.dll but no success
what should I do ?
It depends on which version of Tess4j, you are currently using .
Let's say, version 3.2.1 worked well with 2010 VC++, but for version 3.4.1, you need to upgrade to VC++ 2013.
Its is all about the compatibility of the DLLs with the VC++ version. Use Visual C++ 2017 Redistributable for Tess4J 4.x.
