好吧，我很難過。 我正在爲智能安裝製造商編寫一個安裝支持插件，它將爲我安裝一些組件 - AlphaControls :)德爾福組件安裝實用程序控制臺應用程序
而附件是一個控制檯應用程序。但出於某種原因[在代碼中]向「已知軟件包」註冊表位置添加軟件包，它希望添加一個額外的註冊表項，即使數組大小僅設置爲3.它正試圖添加一個.DPK文件，即使該數組是爲.BPL設置的。 Soo ...什麼地獄？ 它的作品和所有，除了最後嘮叨的一點，它試圖添加。 編譯大小約爲97/98k，優化和壓縮後縮小到約48k
所以我想我的問題是，任何人都可以發現我似乎忽略的錯誤？ 是的，我知道設置，但是...我已經花了錢在智能安裝製造商，所以我得使用它。
沒有編譯錯誤，甫一增加了一個額外的非.bpl文件到註冊表
代碼如下...
