CreateToolhelp32Snapshot不适用64位进城。
MSDN原文：

th32ProcessID
If the specified process is a 64-bit process and the caller is a 32-bit process, this function fails and the last error code is ERROR_PARTIAL_COPY (299).

用EnumProcesses取得进城ID，然后调用上面的GetProcessPath(...)

以下是EnumProcesses的 MSDN Sample Code，很简单，翻译一下就行。

#include <windows.h>
#include <stdio.h>
#include <tchar.h>
#include <psapi.h>

void PrintProcessNameAndID( DWORD processID )
{
    TCHAR szProcessName[MAX_PATH] = TEXT("<unknown>");

    // Get a handle to the process.

    HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |
          PROCESS_VM_READ,
          FALSE, processID );

    // Get the process name.

    if (NULL != hProcess )
    {
        HMODULE hMod;
        DWORD cbNeeded;

        if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod),
          &cbNeeded) )
        {
          GetModuleBaseName( hProcess, hMod, szProcessName,
          sizeof(szProcessName)/sizeof(TCHAR) );
        }
    }

    // Print the process name and identifier.

    _tprintf( TEXT("%s  (PID: %u)\n"), szProcessName, processID );

    CloseHandle( hProcess );
}

void main( )
{
    // Get the list of process identifiers.

    DWORD aProcesses[1024], cbNeeded, cProcesses;
    unsigned int i;

    if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
        return;

    // Calculate how many process identifiers were returned.

    cProcesses = cbNeeded / sizeof(DWORD);

    // Print the name and process identifier for each process.

    for ( i = 0; i < cProcesses; i++ )
        if( aProcesses[i] != 0 )
          PrintProcessNameAndID( aProcesses[i] );
}
