Everytime I try to extract files, AVG and Norton give me an error and delete the MaxKO.exe file. What should I do?

Turn off your Antivirus or uninstall your antivirus

Ur antivirus deletes it.
Run game via .exe not launcher

Go into you anti virus, and look for deleted files/vault of some sort, you should see the file, then mark it as safe.. then it should work without having to turn anti virus off.

You dotn need use winrar only click and install
