It's exactly like they said. the bypass tutorial is on the first page. but I will explain here.
1. download process explore and open it.
2. open GC and leave on server selection screen
3. in the process explorer, look for grand chase, double click, go to threads and click start address.
4. look for processes with the same name, click on them one at a time and suspend.
done that just open the cheat engine file and be happy
