FBX batch tool

Hello guys,
I´m ussing FBX batch tool for convert 3d models from Inventor to Blender *.fbx.
I´m stuck right now because this notice:
Couldn´t find 3ds Max instalation. Do you have version 2018.4 or later installed?
If I put the link to 3ds Max it still doesn´t work.
My version of Inventor and 3ds Max is 2021.
