The dll's you refer to are CRT (C Runtime dll's) so it's hardly likely you will benefit from looking at these. Chances are, your serial is not imbedded in the application, so looking for it may be useless. Does this app have .net component dll's that you can dump via ildasm and check for logic to bypass serial / license checking? Or does the app supply a more normal dll that you can dump and look at? Finally, if you can do it, you can trace, debug .net applications.

Just wondering - what would be the point of finding the serial number? From what I can gather, you need to join their site anyway, to get anything other than the demo media. Oh well, just wondering.

As for registering: 5 mins on a 98 box with trusty softice and a few spots of olly gave me this.

Open options, go to register. Don't give it a number, use register without internet access or whatever it's called. That'll show you a second dialog. This time, just input whatever, and hit ok. Wait for it .... and smack, there's a good old fashioned messageboxa. Bpx in softice, trace,trace,trace and you're in usercode. Note the spot, use olly to attach, find the spot in olly, scroll up a bit, and what do you see? A conditional jump going right past the msg box. And from where the jump ends? Not far to a call that says something like register.
Having done it, figured I'd just force the jump by giving it my return code (a 1, typicall) and boom - it crashed. But that's just coz the prog is error prone, on startup again, the options dialogue told me I was registered, and that it was the "members are". Go figure.

Anyway, I have no interest in the program, so I don't bother checking if it really thinks I'm registered or not. I already uninstalled it, so I can't even check it. Don't think it's worth it either.
