Hi! I found on the net this funny crackme! I bypass almost antidebug tricks: inline hooking, Hardware breakpoints detection and int3 scan with other thread (Very Bad, if the prog is under debugging, modifies some locations used to calculate the serial making it unusable);but i have a question: if i put the correct serial, the dialog form answers with a "Reg Data Checking..."? Clearly, i understand the routine behing Reg Code [10:15]... (serial's form: ********-*****-***)

Hi! I stop in to decrypt routine to generate 'Registered...' message. Analysing the code in Olly, i expect that the initial address stays in the range of 0x004548XX offsets because this block ( long more or less 0x68 bytes...) is clearly encrypted.But all serials (i.e xxxxxxxx-0c01-xxx or xxxxxxxx-0C03-xxx),calculated by this supposition, don't generate the right code! I forgot anything ?

Hi, after a deeper analysis i found the solution! I'have forgot to consider the only address initialized in the other thread! But now the message 'You real a good cracker! Respect! ' appears ... ;)

As a_tek7 suggested me, there's a little bug in my keygen cause an error about format string parameter passed to wsprintf() function: %8X indeed %08X! Sorry for this mistake ...!
