Windows Server 2012更新补丁后导致Micosoft ODBC for Oracle出现问题

The Oracle(tm) client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3 (or greater) client software installation.

搜索了网上大量资料，折腾、尝试了很多方法（下面链接），始终无法搞定，后面在服务器上重装了Oracle 11g Client后，问题终于解决。特此记录一下。 到目前为止，不清楚为什么补丁突然影响了这个驱动。其实我们在折腾过程中，更换访问Oracle的驱动，是没有问题的。唯独使用Microsoft ODBC for Oracle访问ORACLE数据库受到影响。
