If you are sure that you will never modify your licence file using a DLL call SetVal / AddModule / DeleteModule, you can protect the content of the licence file by using the <AllowSetVal>No</AllowSetVal> in the project file or setting this option in the detail page within the Licence Generator. This blocks modifying important information via SetVal like adding new licences or modules.

 

Activation Keys can be used any time but a hacker would not be able to modify the licence file using the licprotector.dll (even in case of stealing the PSK/Read Key) and make a generic program to modify licence files.
