Currently, we are providing the license key as version and platform specific. Due to this, for each new volume release, need to generate the license key and register it in the application to avoid the license error. It seems to be something odd.
Hence, we should provide the backward compatibility support to the license key. So that, the latest generated license key will work for the older versions too which avoids to generate and register the older version license key based on versions if older version applications are maintained.
