What Debug check it does?

Hi, I saw that this new version of styleXP has come out, I tryied to debug it with olly but it goes out ......seems to be some Debug Check, I found that it uses IsDebuggerPresent and I worked around it, I saw that at

00428DFB CC INT3
00428DFC . FFD6 CALL ESI
00428DFE . 57 PUSH EDI

is that INT 3, I tryed to nop it but no success, anyone has got lost time to follow me in that trick? thanks in advance loman

Make sure that in the debugging options under exceptions you checked marked INT3 Breaks by Ignore Following Exceptions.
If you do that the program will run fine in olly, ofcourse run the program with the isdebuggerpresent plugin
