Kliknout na Activate.exe. Připojí se to na stránky výrobce a ohlásí "Succesfully activated". To nefunguje? Aspoň to tak píšou v readme.txt, který jste si stáhl.

Unzip the package you`ve downloaded and run the activation program
Activate.exe which is included in the package, then run Setup.exe to
install the software.
You have to install it before the Giveaway offer for the software is over.
