安装WIA组件

下载地址：

http://pan.baidu.com/s/1bnGU5Nx

安装方法：

将下载后的WIAAutSDK.zip解压，复制wiaaut.dll到C:\Windows\System32，注册组件"regsvr32 wiaaut.dll"

测试代码：

'save as wia-installing-test.vbs
On Error Resume Next
    Set wia = CreateObject("WIA.ImageFile")
    If Err.Number =  Then
        MsgBox "wia installing ok",, "wia installing test"
        Set wia = Nothing
    Else
        MsgBox "wia installing failed",, "wia installing test"
    End If

ps：一般来讲只有ghost xp系统会缺少这个组件。
