[QUOTE]Originally posted by Wurstgote
[B]It's me again . First I've tried to follow britedreams suggestions, but either his ideas were way beyond my head or Win XP behaves different than Win 2K.; so I had to do it on my own. I've loaded the dumped app into Olly and let it run. As soon as I try to access the "Options" in the "Tools" menu, Olly pops up with an access violation at 57891e. The code around looks like this: 0057890C /$ PUSH EBP 0057890D |. MOV EBP,ESP 0057890F |. PUSH ECX 00578910 |. PUSH EBX 00578911 |. MOV EAX,DWORD PTR DS:[40781E] ;<&kernel32.GetModuleHandleA> 00578917 |. MOV EBX,DWORD PTR DS:[EAX] 00578919 |. PUSH DWORD PTR DS:[EBX] 0057891B |. MOV DWORD PTR SS:[EBP-4],EBX 0057891E |. POP DWORD PTR DS:[EBX] 00578920 |. MOV EAX,DWORD PTR SS:[EBP-4] 00578923 |. POP EBX 00578924 |. POP ECX 00578925 |. POP EBP 00578926 \. RETN So I've put a breakpoint on 578911 and single-stepped through the code. ----------------------------------- you should bp 578911 in the orignal and follow the [40781e] to find the correct value. on your pc 578911 is the correct address for code that I changed in my earlier post.
