Hi @sgitalia007, what this message means is that the app that you are trying to use requires an older version of our hand tracking software. The Leap Motion Controller is compatible with all of our current hand tracking releases so all you will need to do is uninstall this version and install the version that the app requires. Please see some links below to save you time searching for these:
V2 (Requires a manual hotfix to be applied)
V3
V4
