Question

我正在尝试从VS2012中的空白Web表单模板构建示例Web应用程序，并将PDFNet dll添加到其中。如果我在.NET 3.5中运行该项目没问题。如果我在.NET＆gt; = 4中运行它，我会收到此错误：

无法加载文件或程序集“PDFNet64”或其依赖项之一。试图加载格式不正确的程序。

这是堆栈跟踪：

我已经在网络和Google群组中进行了大量搜索，我已经尝试过这些解决方案（其中包括）THIS，例如THIS

我正在运行Windows 8 x64 PC，我在我的机器上安装了Visual c + + 2010 x64可再发行组件。我还尝试过从pdftron.com下载的示例提供的控制台应用程序，这些应用程序在所有版本的.NET中都可以正常工作。我已经尝试创建自己的控制台应用程序，这也适用于所有版本的.NET。我当时认为这可能是VS2012开发服务器在x86模式下运行的错误，所以我建立了一个IIS网站并从那里运行它，但仍然是同样的问题。我有点失去了，有没有人有任何想法？感谢名单。

Answer 1

由于家伙@ pdftron.com的支持，问题得到了解决。 Here是解决方案。在我的特定情况下，我将IIS设置中的“启用32位应用程序”应用程序池设置设置为True，这与x64版本的PDFNet.dll有些冲突。将其重置为false可解决问题。

Answer 2

通过制作DLL＆＃34;复制本地＆＃34;设置为True解决了我的情况。 IIS应用程序池还需要支持32位。
