madlogik on 3:01 AM 02/22/2019: Changing the push data from "Try Again" to the serial makes a bad try a keygen straight to the messagebox ;)
(In the try again change the push from : PUSH 405034 to: PUSH 19F744 )

zaturion on 6:28 PM 02/26/2019: Hey guys, this was my first CrackMe I solved and I wondered about your comments because they are all wrong, or atleast partially wrong.
The solution is:
1. convert your Windows-Username to ASCII-Code, sum them up and add (X*100000) where X is the usernames length in characters.
2. Repeat Step 1. for the name you have chosen in the crackme.exe
3. Add both sums together and add "31337"
Thanks for the riddle, was really fun and took me some hours as I just began researching reversing :)
thoonline on 3:12 PM 03/08/2019: zaturion - agree with you.
TheBrokenWasp on 7:33 PM 06/11/2019: How come everybody make keygens? I mean I just found and removed the key cheek so I can type in anything I want :S
TheBrokenWasp on 7:38 PM 06/11/2019: Nevermind I just read the faq... Where would I find programs designed to be patched?
