未解决 [求助]傀儡进程问题

我写了一个傀儡进程的代码，但是以不同的exe创建进程时，有时能跑起来，有时程序就直接运行错误了，是哪里有问题啊？
代码：
// 傀儡进程.cpp : 此文件包含 "main" 函数。程序执行将在此处开始并结束。
//
#include <iostream>
#include "pe.h"
#include <Windows.h>
#include <stdio.h>
int main(int argc, char* argv[])
{
typedef unsigned long(__stdcall *pfZwUnmapViewOfSection)(unsigned long, unsigned long);
char pszError[256] = {0};
char* ShowName = (char*)"d:/3.exe";
char* RealName = (char*)"d:/1.exe";
DWORD dwCode = 0;
//这里少了6条代码，老是提示携带了那个啥。
//就是定义了一个卸载函数指针，上下文变量，和创建进程需要的两个结构体
//并且初始化了必要参数
//挂起方式创建进程
//1是正常
if (!CreateProcessA(ShowName, NULL, NULL, NULL, FALSE, CREATE_SUSPENDED, NULL, NULL, &si, &pi)) {
sprintf(pszError, "错误码：%x", GetLastError());
MessageBoxA(0, "创建进程失败了。", pszError, MB_OK);
return 1;
}
//获取context
if (!GetThreadContext(pi.hThread, &context)) {
sprintf(pszError, "错误码：%x", GetLastError());
MessageBoxA(0, "获取线程上下文错误。", pszError, MB_OK);
return 1;
}
//读取原进程ImageBase
DWORD dwImageBase = 0;
ReadProcessMemory(pi.hProcess, (LPCVOID)(context.Ebx + 8), &dwImageBase, 4, NULL);
//获取卸载函数，卸载外壳
HMODULE m = LoadLibrary(TEXT("ntdll.dll"));
if (m == NULL) {
sprintf(pszError, "错误码：%x", GetLastError());
MessageBoxA(0, "加载DLL失败。", pszError, MB_OK);
return 1;
}
ZwUnmapViewOfSection = (pfZwUnmapViewOfSection)GetProcAddress(m, "ZwUnmapViewOfSection");
//0是正常
dwCode = ZwUnmapViewOfSection((DWORD)pi.hProcess, dwImageBase);
LPVOID pFileBuff = LoadFileBuff(RealName);
LPVOID pImageBuff = CopyFileBuffToImageBuff(pFileBuff);
DWORD ImageBase = GetImageBase(pFileBuff);
DWORD SizeOfImage = GetSizeOfImage(pFileBuff);
DWORD OEP = GetOEP(pFileBuff);
LPVOID pAllocAdd = NULL;
for (DWORD i = 0x0;; i += 0x10000) {
pAllocAdd = VirtualAllocEx(pi.hProcess, (LPVOID)(ImageBase + i), SizeOfImage, MEM_RESERVE | MEM_COMMIT, PAGE_EXECUTE_READWRITE);
if (pAllocAdd) {
break;
}
}
if ((DWORD)pAllocAdd != ImageBase) {
//修复重定位表。
RepairReloc(pFileBuff, (DWORD)pAllocAdd);
ImageBase = (DWORD)pAllocAdd;
}
//复制到新创建的进程
//1是正常
if (!WriteProcessMemory(pi.hProcess, pAllocAdd, pImageBuff, SizeOfImage, NULL)) {
sprintf(pszError, "错误码：%x", GetLastError());
MessageBoxA(0, "写入ImageBuff失败", pszError, MB_OK);
return 1;
}
//更改入口点和镜像基址
context.Eax = ImageBase + OEP;
//1是正常
if (!WriteProcessMemory(pi.hProcess, (LPVOID)(context.Ebx + 8), &ImageBase, 4, NULL)) {
sprintf(pszError, "错误码：%x", GetLastError());
MessageBoxA(0, "写入ImageBase失败", pszError, MB_OK);
return 1;
}
if (!SetThreadContext(pi.hThread, &context)) {
sprintf(pszError, "错误码：%x", GetLastError());
MessageBoxA(0, "写入eax失败", pszError, MB_OK);
return 1;
}
//恢复进程
ResumeThread(pi.hThread);
dwCode = GetLastError();
printf("主进程\n");

以3.exe文件创建程序，启动失败。
以1.exe文件创建程序，启动成功。
3.exe是从一个网站工具里面复制出来的notepad.exe
1.exe是一个小葵编码工具。
这是什么问题啊？
