If this is is the first installation on the machine you will need to specify an inventory location. Enter the inventory location, like "/u01/app/oraInventory" and click the "OK" button. In our case we had database installed previously on the same machine hence it didn’t ask for inventory location.

Select the "Skip Auto Updates" options, then click the "next" button.

Enter the middleware home ("/u01/app/oracle/product/12.2.1") and click the "Next" button.

Accept the "Fusion Middleware Infrastructure" option by clicking the "Next" button.

Wait for the prerequisite checks to complete. If there are failures, correct them and rerun the checks. If there are no failures, click the "Next" button.

Enter your support details, or leave it unchecked the security updates checkbox. Click the "Next" button. If you chose not to receive security updates, click the "Yes" button on the warning dialog.
