RC Simulations were as good as their word, the postman duly delivered FSX this morning. My ancient built in DVD drive was very reluctant to read disc 1, but finally managed it. However, no way would it read disc 2, so I had to cancel and roll back the installation. Then off to PC World, I've bought an external DVD which plugs into a USB port. This has been duly installed, it read disc 1 first time, and it is busy reading disc 2 as I write. I guess at least I will be able to use this box for other things, but at the moment its an extra cost of FSX. Frank T.
