PowerShell中獲取MSI信息

Question

我試圖從一個MSI的一些信息文件中像ProductCode或CustomAction。我使用了來自互聯網的其他腳本並對它們進行了編輯，但我的腳本存在一些問題。

這僅僅是一小片的原代碼，但如果我執行此，我收到此錯誤信息：

警告：異常調用「InvokeMember」和「5」的說法（S）：「的OpenView，SQL」的

MSI-數據庫不支持LIKE因爲它僅實現了SQL語言（https://msdn.microsoft.com/en-us/library/windows/desktop/aa372021.aspx）的一個子集。這應該工作：

$Query = "SELECT $SELECT FROM $FROM WHERE $WHERE = 'ProductName'" 

如果您需要過濾，你必須做它的SELECT * FROM Property結果。
