Oracle11g 客户端 SQL Navigator 出现Cannot load OCI DLL: oci.dll Install an Oracle Client. It is .......

SQL Navigator 出现如下错误：

Cannot load OCI DLL: oci.dll

Install an Oracle Client. It is essential to setup an Oracle client before running SQL Navigator. Please refer to SQL Navigator Installation Notes for more information.

原因在于SQL Navigator 是32位的，对应的Oracle客户端也应该安装32位，这个32位与电脑是64位无关，详细内容之后分析。

解决办法，安装Oracle11g32位客户端
