【中文标题】Office Interop PowerPoint E_NOINTERFACE 注册表错误【英文标题】：Office Interop PowerPoint E_NOINTERFACE registry fault 【发布时间】：2015-09-30 20:04:01 【问题描述】：

无法将“System.__ComObject”类型的 COM 对象转换为事件接口类型“Microsoft.Office.Interop.PowerPoint.PresEvents_Event”。此操作失败，因为 IID 为“9826398E-2574-3EDD-9717-A913EE28A41D”的接口的 COM 组件上的 QueryInterface 调用因以下错误而失败：“不支持此类接口（来自 HRESULT 的异常：0x80004002 (E_NOINTERFACE) )'并且COM组件不支持IID为'91493463-5A91-11CF-8700-00AA0060263B'的源接口。

我有两个将 PPTX 转换为 pdf 的 smilar 网站。他们使用相同的代码和相同的 dll 进行操作。一个网站用于概念和实验，而另一个用于商业。

实验的一个完美，但另一个有问题。

我使用相同的代码相同的 dll，但它永远不会工作

两个站点在同一个应用程序池上运行。

转换代码是：

var powerpointApp = new Microsoft.Office.Interop.PowerPoint.Application();

var powerpointDocument = powerpointApp.Presentations.Open(@"C:\PowerPoint.pptx", 
                Microsoft.Office.Core.MsoTriState.msoTrue, //ReadOnly
                Microsoft.Office.Core.MsoTriState.msoFalse, //Untitled
                Microsoft.Office.Core.MsoTriState.msoFalse); //Window not visible during converting

powerpointDocument.ExportAsFixedFormat(@"C:\NewPDFFile.pdf", 
                Microsoft.Office.Interop.PowerPoint.PpFixedFormatType.ppFixedFormatTypePDF);

powerpointDocument.Close(); //Close document
powerpointApp.Quit();

问题的实际原因是基于互操作 dll。
