我一直收到这个错误： 未找到Oracle客户端和网络组件。这些组件由Oracle Corporation提供，是Oracle 7.3.3或更高版本客户端软件安装的一部分。
在安装这些组件之前，提供程序无法运行。
当我运行我的应用程序时作为例外。
该应用程序针对的是32位计算机，计算机实际上是64位。
这在昨天和两个月前工作正常，现在它不起作用它不断抛出这个错误。
我已经仔细检查了我的ORACLE_PATH，并确保我存在oci.dll以及ociw32.dll，实际上它们位于Oracle11gcli / bin文件夹和orcle11g / bin文件夹中
我可以使用sqlplus和sqldeveloper进行连接。 当我登录到sqlplus时说64位生产，但我怀疑32/64位架构是问题，因为它工作了3个多月就好了。
tnsnames和listener文件看起来都很好。
我错过了什么？
以下是例外：
