無法加載文件或程序集「PDFNet」或其某個依賴項。試圖加載格式不正確的程序

我試圖從VS2012中的空白web表單模板構建一個示例web應用程序，並將PDFNet dll添加到它。如果我在.NET 3.5中運行該項目沒有問題。如果我在.NET> = 4中運行它，我會看到以下錯誤：無法加載文件或程序集「PDFNet」或其某個依賴項。試圖加載格式不正確的程序

無法加載文件或程序集「PDFNet64」或其某個依賴關係。試圖加載格式不正確的程序。

這是堆棧跟蹤：

我已經搜查了很多在網絡和谷歌組，我已經嘗試了這些解決方案（在其他人中），THIS和例如THIS

我正在運行Windows 8 x64 PC，並且我的機器上安裝了Visual C++ 2010 x64可再發行組件。我也嘗試了從pdftron.com下載的示例提供的控制檯應用程序，並且這些應用程序在所有版本的.NET中都可以正常工作。我曾嘗試創建一個我自己的控制檯應用程序，並且也適用於所有版本的.NET。然後我認爲這可能是VS2012開發服務器在x86模式下運行的錯誤，所以我建立了一個IIS網站並從那裏運行它，但仍然是同樣的問題。我有點失落，有沒有人有任何想法？感謝名單。

在您的IIS站點嘗試將AppPool設置爲在32位模式下運行 – 2013-03-19 12:13:50

您的意思是「高級設置」下的「啓用32位應用程序」設置爲true？已經嘗試過，沒有運氣。我使用的PDFNet DLL無論如何都是x64 dll。 – 2013-03-19 12:28:56
