Over the past 5 years of being on the net, all the knowledge I have gained has been through communication of some kind especially forums.

It's about time I learn some cracking.

My first program is something similar to installshield. I need to verify the serial to extract the files.
Does anyone know of a brute force program that could run a scheme to click the ok box then input another password until the serial is correct and save the correct serial number once done.

An old program like fakesurf meant for cheating pay for surf companies had the ability to remember mouse movement and ultimate zip cracker (UZC) together would work perfect.
Does such a program exist to brute force and reclick a the popup invalid serial number error until success is achieved?

Keep up the great Woodmann

Hello WannaBCracker !

Of course there are such programs. But I really don't know why anybody would use such a thing.

Let's see it very positive and say the program can test two passwords in a second. (because we assume there is no delay or quit after three false serials) Let's assume the serial is only a ten-digit number. So it would take (9999999999-1000000000)/2 seconds to bruteforce it. This example would take 142 years to get the right serial.

And if you finally have it, how do you know that the screen after the password prompt does not show the license contract and the default button is set to "Decline"? So the next <Return> send by the bruteforcing program would exit the installer.

You're assuming that brute-forcing the password is the only way to approach this. And you haven't included the name (and url) of your target, so nobody can point you in a different (and possibly-easier) direction.

Are there already tutorials out there that discuss the protections used by this company?

Look at the code to see what the program does with your entered password. How does it cross-check the serial? That's what reversing is all about.
