Error in Windows Server 2008: cannot load OCI DLL, 126

Oracle 11g R2 is installed on Windows Server 2008 server. When using Navicat to connect Oracle, the following error will be prompted:

Cannot load OCI DLL, 126: Instant Client package is required for Baic and TNS connection ,
For more information: http://wiki.navicat.com/wiki/index.php/Instant_client_required

According to the above link page, Navicat only supports 32-bit instant client. Therefore, although we have installed 64 bit Oracle, we need to download a 32-bit client as Navicat only supports 32-bit http://www.oracle.com/technetwork/topics/winsoft-085727.html 。

Here is the complete solution:

Step 1: download the file from the above address: instantclient-basic-nt-,
