Description

..::[FaTmiKE 2o24]::.. Welcome to my 5th crackme! It took a long time implementing this, i hope it is hard to solve! Sorry for the long load time of the crackme :) Here are the goals: 1. The main goal is to unpack and uncrypt this crackme. 2. Find a valid serial or write a keygen. The crackme was tested on windows 10. Have fun! Known Issue: The crackme has to be started from explorer.exe
