Yes, each software application has its own licence file and the complete licence AND software copy protection information is stored within the licence file.

Beginning with the version 2.3, even applications with different DLL versions of Licence Protector can be used on the same machine, because the PROGID of the DLL changes with every main release (but the DLL name LicProtector.dll is still the same). We recommend, that you store the DLL within the folder of your application and not on ..\windows\system32
