It's a Compaq laptop. I have installed FSX on this laptop before, so I don't see why FS9 should have problems. It says I have 122 GB free out of 200 GB, once again shouldn't be a problem. We bought this laptop in the winter of 08-09 and that's when I installed FSX on it. I guess I'm installing it to program files, because it's just the default "express" installation. There is only one account on this laptop. All I did was insert the disc, click on run setup.exe and continued through the installations.
