使用Lua脚本禁用桌面合成

我正在使用IndigoRose的Set-Up Factory来构建我的安装程序。Set-up factory在安装程序的脚本部分使用lua语言。现在，对于我的应用程序，一旦安装完成，我希望运行一个脚本，如果操作系统是Windows 7，则禁用桌面分解。有没有办法我可以在lua中访问dwmapi.lib来实现它呢？ 有没有系统库函数可以访问桌面窗口管理器？

我已经做过一些谷歌搜索，并找到了以下vbscript代码...

Private Const DWM_EC_DISABLECOMPOSITION As Long = 0
Private Const DWM_EC_ENABLECOMPOSITION As Long = 1

Private Declare Function DwmEnableComposition Lib "dwmapi" (uCompositionAction As Long) As Long

Private Function SUCCEEDED(hr As Long) As Boolean
    SUCCEEDED = (hr >= 0)
End Function
Private Function FAILED(hr As Long) As Boolean
    FAILED = (hr < 0)
End Function

Private Sub Form_Load()
    If SUCCEEDED(DwmEnableComposition(DWM_EC_DISABLECOMPOSITION)) Then
        MsgBox "Vista Aero est Desactive"
    Else
        MsgBox "Vista Aero n'a pas pu etre Desactive"
    End If

End Sub

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
    MsgBox Cancel
    MsgBox UnloadMode
    If SUCCEEDED(DwmEnableComposition(DWM_EC_ENABLECOMPOSITION)) Then
        MsgBox "Vista Aero est Active"
    Else
        MsgBox "Vista Aero n'a pas pu etre active"
    End If

End Sub

我该如何在LUA中实现这个呢？
