Topic created on: January 23, 2011 15:56 CST by Funuter .

I am trying to patch a simple, unpacked program. I patch the few lines of code, when I try to "Copy to Executable", it gives me the message "Selection contains modified fixups. When loading this DLL, OS will adjust fixups, thus modifying your code...etc...Do you still want to update this executable file?". I say yes (no won't let you save) and it modifies it to make it unusable, usually DB'ing my code. Help! OllyDBG 1.10

BTW No plugins installed.

mybe the code where you patch is  in the heap.so you can't save. mybe the program is packed. you should first unpack it.

The memory address to be patched/dumped must exist within ranges of raw file sections (On disk, not in memory). Refer to the section header for values of RawOffset and RawSize and do some math.

N.B. Also, Keep in mind the File Alignment value of your PE.
