Ok firstly you do something with the exe at runtime, you could see this in both the pcode version and native which prevents Olly from debugging. Mostly I would assume it's for the InitCommonControls since you have that imported. Either way it fucks up cause GetCurrentProcess() is called and it gets the process handle of Olly and not your crackme and fails to locate the resource successfully and all that jazz. (My assumption.)

Anyway, run it without Olly then attach after it's running to debug.

I can say this is a bit more creative then the other typical crackme's. Only thing is you are using MD5 which I'm not going to bother reversing as you can't "reverse" MD5, it is a hash.

Anyway your main button control calls another function to do the compare so the error message is not in the same call as the compare. The compare can be found at:
