当在64位系统上安装32位Devart驱动程序和32位Oracle客户端时，可能会遇到连接Oracle的问题。解决方案是确保.NET应用程序的构建选项设置为X86，而非默认的AnyCPU。

"Can not obtain Oracle client information from registry. Make sure that Oracle Client Software is installed, or use Direct mode of connecting to server."在使用 Devart访问Oracle的时候，突然conn无法open了，报出这个错误，原因是把编译环境给由4.5更换为2.0后引起的，切换回去后也不行了，一直百思不得其解，后来google到原因了。具体解决方式见下：This problem comes to the surface when you have installed a 32-bit Devart driver together with the 32-bit Oracle client on a 64-bit system.

When you have this combination, you need to make sure the build options of your .NET application/unit test is set to X86. By default, the build option will be set to AnyCPU. If this is the case, you will receive the above error.
