TIBCO iProcess® Engine 11.10.0

# The Installer Fails with an "Unable to Open the File" Warning

## Problem Description

When you run the installer, a warning dialog box is displayed with the following message:

``Unable to open the file: fil.dll``

You can only click the OK button to this dialog box, and when you do so, the installer exits.

This error occurs if you do not have the correct Oracle database and/or client releases (along with any additionally required patches or components) installed on the computer where you are trying to install the iProcess Engine.

The `fil.dll` file requires the Oracle client `.dll` files to be able to connect to the Oracle database. When the installer starts up, it tries to load the `fil.dll` file, which in turn attempts to load the required Oracle `.dll` files. If these files cannot be found, the error occurs.

## What to Do

Install the required Oracle database and (or) client release on the computer where you are trying to install the iProcess Engine. See Oracle Database for more information.

Note | Make sure that you have also installed any additional patches or components that are required.
