Tell me exactly what you are doing and exactly your set up after installation. tell me exactly what happens after hitting 'exit' on the installer and tell me exactly what happens when you try to run the game.

Please provide screenshots. You are doing something wrong and it's hard to track it down if you believe you are following the instructions.

Here are some hints and tips:

You can know the installer ran successfully by virtue of the fact that you have an FE icon on your desktop and an FE folder in your Rome data folder.

This FE folder is deleted in the final step of the batch file execution after hitting 'exit' on the installer.

Let me know your status and I will try to guide you through manually if necessary.
