Licence Protector 5

Licence Protector 5 offers a sophisticated method to detect if a license file was replaced by an old version of the file.

 

Tamper detection ensures, that the file can not be copied (backup) and then be restored. By default a license file can be backuped, the folder can be deleted and then the file can be copied back. As long as the hardware is the same, this is valid operation and offers an easy way for a reinstallation - see also Allow Reinstallation.

 

Tamper detection would detect, that the file is restored and blocks the application. To use the application again a special key is needed to unlock tamper detection.

 

This feature works in offline mode and can be activated to increase security. It prevents replacing a file  with a previous version of the file. Typically this is only required if you have modules with counter values, which are decreased during runtime. A restore would then result in different counter values.

 

If your application is in evaluation mode and the application is uninstalled and then reinstalled, this is automatically detected and Tamper Detection is not necessary for this situation.  

 

Tamper Detection locks the complete application and you should be aware that this could results in more support calls. Also a reinstallation of the application is not possible. If you store the license file on a USB flash drive and the USB flash drive should be used on different machines, Tamper Detection can not be used.
