Unzip the packages into a single directory such as


    C:\oracle\instantclient_12_2

Add this directory to the


    PATH

environment variable. If you have multiple versions of Oracle libraries installed, make sure the new directory occurs first in the path

Download and install the correct Visual Studio Redistributable from Microsoft. Instant Client 12.2 requires the Visual Studio 2013 redistributable. Instant Client 12.1 requires the Visual Studio 2010 redistributable .

If you intend to co-locate optional Oracle configuration files such as tnsnames.ora, sqlnet.ora, ldap.ora, or oraaccess.xml with Instant Client, then create a subdirectory


    C:\oracle\instantclient_12_2\network\admin

This is the default Oracle client configuration directory for applications linked with this Instant Client.

Alternatively, Oracle client configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN to that directory name.

Start your application.
