Which version for? I've actually been meaning to download one but have been too lazy. Is it also the portable edition?

I opened the message box, press pause in Olly then alt-F9 (Which waits until control goes back to the user), then clicked ok. This brought me to the comparison function, where I found stricmp. The serial was in plain text and visible :p.
@Syntax Error, Great job, that was really fun! :)

Thanks for the ReverseMe, I already lost it when I read the title of the application xD

This is how I solved it:
Observing the crackme, I didn't want to use any string searches so I noticed the sounds which were played when checking the serial.
So I checked out the intermodular calls for the crackme and set breakpoints on every api call that could have to do something with sound.



And after testing a random serial we trigger one of the two breakpoints. That's basically it the picture explains the rest. You can find the serial in the dump at the bottom.

Open RessourceHacker and check out the wave folder. There you can find the sound samples used in the crackme and their id's.



We know the sound with the id 105 (decimal) so lets search for that constant.



And sure enough we land at the exact same spot in memory again.


Edit: Moving thread to C++ Challenges?
