Answer 1

I am a shrimp. Here's why it doesn't work: you decided to abandon the standard Windows headers and incorrectly specified the calling convention.

#include <windows.h>

int WINAPI WinExec(string lpCmdLine,int uCmdShow);

What the WINAPI macro equals depends on the compiler.
What to write in CreateProcess, if anything ...

#include <windows.h>   // убирай этот kernel32.dll

STARTUPINFO si;
PROCESSINFORMATION pi;
ZeroMemory(&si, sizeof(si));
si.cb = sizeof(si);
si.wShowWindow = SW_SHOWDEFAULT;

CreateProcess(NULL, L"c:\\AlertMailer.exe", NULL, NULL, false, 0, NULL, NULL, &si, &pi);
// Мы не ждём ничего от программы — шшас закроем.
// Если хотите дождаться — WaitForSingleObject(hProcess, INFINITY);
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
);

Answer 2

Note This function is provided only for compatibility with 16-bit Windows. Applications should use the CreateProcess function.

Answer 3

Because ERROR_FILE_NOT_FOUND - 2 (0x2) - The system cannot find the file specified.

Answer 4

this is understandable, but it is there, there can be no more reasons?
