C ++ CreateProcess cannot get path from socket on Windows 7 (64)

I am trying to create a simple application controller using the CreateProcess () function. The program gets the te path of the program to be executed by the socket and stores it in the char [] variable, and then sends the variable to the function that will execute it.

The error I am getting is

Client: Received data is: C:\Windows\System32\calc.exe
Server: Bytes received: 30.
CreateProcess failed (123).

      

        
        
        
      

    

(2) = ERROR_FILE_NOT_FOUND

I tried with doble slash (//) and I get error (123)

Client: Received data is: C:\\Windows\\System32\\calc.exe
Server: Bytes received: 33.
CreateProcess failed (123).

      

        
        
        
      

    

(123) = ERROR_INVALID_NAME

The function that gets the path to the program execution:

bytesRecv = recv(m_socket, recvbuf, 200, 0);

if (bytesRecv == SOCKET_ERROR)
   printf("Server: recv() error %ld.\n", WSAGetLastError());
else
{
   printf("\nClient: Received data is: %s\n", recvbuf);
   printf("Server: Bytes received: %ld.\n", bytesRecv );
   NewProcess(1,LPWSTR(recvbuf)); // <---- Call to NewProcess function with path
}

      

        
        
        
      

    

and a function that starts the process:

void NewProcess(int count,LPWSTR cmd)
{
    LPTSTR concatenation = _T(" ");
    LPTSTR cmdArgs = NULL;


    STARTUPINFO si;
    PROCESS_INFORMATION pi;

    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    ZeroMemory( &pi, sizeof(pi) );
    si.wShowWindow = SW_HIDE;
    si.dwFlags = STARTF_USESHOWWINDOW;

    // Start the child process. 

    if( !CreateProcess( NULL,       // Program full path
    cmd,                    // Arguments
    NULL,                       // Process handle not inheritable
    NULL,                       // Thread handle not inheritable
    FALSE,                      // Set handle inheritance to FALSE
    0,                          // No creation flags
    NULL,                       // Use parent environment block
    NULL,                       // Use parent starting directory 
    &si,                        // Pointer to STARTUPINFO structure
    &pi )                       // Pointer to PROCESS_INFORMATION structure
    ) 
    {
        printf( "CreateProcess failed (%d).\n", GetLastError() );
        return;
    }

    // Wait until child process exits.

    WaitForSingleObject( pi.hProcess, INFINITE );
    printf("\nProcess ID: %d Terminated!",pi.dwProcessId);

    // Close process and thread handles.

    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
}

      

        
        
        
      

    

Can you tell me what is wrong, I suppose it is something like variables, but I cannot find the error.

Thanks in advance.
