Installation



See the Instant Client Home Page for more information about Instant Client packages.

1. Download the appropriate Instant Client packages for your platform. All installations require the Basic or Basic Light package.


2. Unzip the packages into a single directory such as instantclient_12_2


3. 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


4. 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. Instant Client 11.2 requires the Visual Studio 2005 redistributable.


5. Start your application.



ODBC users should follow the ODBC Installation Instructions.
