Hi, I have c++ console application, but it works only on 64bit systems. Please help me to find solution for this problem.

Make sure you compile it for 32-bit.
What is the output of the program on 32-bit system if compiled 32-bit?

It works on both ( I mean I can launch it ) but it patches offsets only in 64bit version of windows.

What is exact failure? Do you check the results of WriteProcessMemory?

well, I can see result... it is not patching memory as it should be on 32bit systems.

You need to find out whether the offsets are wrong, or just WriteProcessMemory() calls fail.
#define PATCH(i,w,l) do { if (!WriteProcessMemory(hProc,reinterpret_cast<LPVOID>(gameBase+i),w,l,&dSize)) printf("PATCH: %d\n",GetLastError());} while(0)
#define NPATCH(i,w,l) do { if (!WriteProcessMemory(hProc,reinterpret_cast<LPVOID>(i),w,l,&dSize)) printf("NPATCH: %d\n",GetLastError());} while(0)

Explain me:
1. do you have both 32-bit and 64-bit OS?
2. what is the bitness of WAR3.EXE on all systems?
3. what is the bitness of your patching application on all systems?
4. are the offsets known to be good for both 32-bit and 64-bit WAR3.exe?

Also, what is the output on working and not working systems.
