I have a related but different problem.

I just purchased FSX Deluxe Edition, but am having difficulty installing the
program. When I insert the DVD into the DVD drive, all I see is a Readme.txt
file with the following statement, "This disc contains a "UDF" file system
and requires an operating system
that supports the ISO-13346 "UDF" file system specification."

This is as far as I can get. I have checked my system with the
fsinsider.com website and it returns that my computer far surpasses the
minimum requirements to install and run the game. Can anyone help?
