When you open the program GAMS.exe, you will be asked for Username and Password. By Default, Username:Password is Bimal:bimal. So, when the program is fully loaded, There you will see Trial version. So our task is to find the Full Version Key for this software. Here it begins....
- Fire up GAMS.exe on Ollydbg.exe and run the the program by Pressing F9
- Now Click रजिषटर inside सेटिङ Menu.
- A Register dialogue box will appear. You are asked for Product Code for registration while Machine Code is self generated uniquely for each pc's.
Enter fake Product code ( In my case '777777777') But Do not click Register Button now. - In ollydbg, click E (As you see below menu bar - L|E|M|T|W|H|C... )
- There you search for -MSVBVM60.dll- then right click on this file and select (View names)
- Under Names in MSVBVM60, Search for __vbaStrCmp and put breakpoint on it by pressing F2
- Now you click Register Button on the Registration dialogue where you entered Fake product Code.
- As you hit the Register Button, Ollydbg will fire on the Breakpoint on vbaStrCmp where you will see your fake product key and the real product key being ready for compare.
- There you have a real Full Version product key on the Register's view.
- Happy Reversing....
