-------------------------------------------------------------------------------
Install the program and then, click 'Help' then 'About ByteCatcher' then 
'Register' to pop-up the registration window. Enter the following info.

Registration No.: 54545454
Name            : evc_viper
Company Name    : Home

Ok. Fire-up Soft-Ice and set a breakpoint by typing 'bpx getwindowtexta'.
Press 'x Enter' to exit Soft-Ice.

Now, click the 'OK' button and you are back into Soft-Ice. Press 
'x enter' 2 times and F11 to get back to the caller. 

Press 'F10' several times until you get to 0042A72C.

:0042A72C 6888D14A00              push 004AD188

type 'd 4AD188' and you will see '239856538576' in the data window.

:0042A731 8B4DF8                  mov ecx, dword ptr [ebp-08]
:0042A734 83C15C                  add ecx, 0000005C

type 'd ecx', you will see the memory address that holds your fake 
registration code.

:0042A737 E8648AFDFF              call 004031A0 ; <-- compare routine
:0042A73C 85C0                    test eax, eax
:0042A73E 7564                    jne 0042A7A4

:

Bla.h..Blah...Blah....

So, get out of Soft-Ice and enter

Registration No.: 239856538576
Name            : evc_viper
Company Name    : Home

and the program is registered under your name. Well, this program doesn't show
you the usually "Thank you for registering" messagebox. Anyway, Job done.


Final Note:
   After I cracked this program, I use W32DAsm to get a dead-listing of it.
   Without doubt, the registration code is hard-coded in the program. The user 
   name, Company name have nothing to do with the real registration code.

   I couldn't believe that in today, there are still programmer hard-coded
   the registration code inside their program.


Ob Duh
   Do I really have to remind you all that by buying and NOT stealing the 
   software you use will ensure that these software houses will continue to
   produce even *better* software for us to use and more importantly, to
   continue offering even more challenges to breaking their often weak
   protection systems.
