I'm not exactly sure why this didn't work, but what I did was simply install the 32-bit and 64-bit versions of ODAC 11.2 Release 5, which took care of registering all required assemblies in the GAC, among several other tasks I'm sure. Once installed, I ran the app, and it worked fine. Thanks to all that have contributed to this.

我不确定为什么这不起作用，但我所做的只是安装 ODAC 11.2 第 5 版的 32 位和 64 位版本，它负责在 GAC 中注册所有必需的程序集，以及其他几个任务我确定。安装后，我运行了该应用程序，并且运行良好。感谢所有为此做出贡献的人。

You need enable it for 32 bit application in the application pool your website from IIS.

您需要从 IIS 为您网站的应用程序池中的 32 位应用程序启用它。

open IIS>application pool> Enable 32 bit application= true

打开IIS>应用程序池>启用32位应用程序=真
