The will show you the System Properties dialog. Click on Environment Variables

On the Environment Variables dialog:

• amend the PATH environment variable to include the Oracle Client directory (eg. d:\Oracle_Client)
• set the TNS_ADMIN environment variable to point to the Oracle Client directory (eg. d:\Oracle_Client)
