Hi I just bought Freespace 2 and its not letting me install it on my computer. When I try to install it it comes up with this message C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose "Close" to terminate the application. The options are Close and Ignore. If anyone can offer me any help on this I would be grateful. Please reply to danieltipping@hotmail.com
