Hi,
Im following this guide http://resources.infosecinstitute.com/reverse-engineering-ollydbg/ ("http://resources.infosecinstitute.com/reverse-engineering-ollydbg/") In order to bypass a simple software that looks for a .KEY file.
In the guide the messageboxa is called from "software..." and when they trace this and subsequently modify the actual line of code that is responsible for producing the error message, they save changes to the .exe.
3020
Problem is, I can follow this guide exactly, but when I finish it wants to save my changes as a system32 DLL file! (mfc42.dll)
Below is a screenshot of my messageboxa and it appears to be calling from the DLL in question:
3019
I know this is probably annoyingly basic but can anyone point me in the right direction?
Cheers
