FS2K needs something approaching 612mb of space on your hard drive to load it. If you are using PRO that is, but you will still need 500mb for the standard. That could be one problem.
Then you need a minimum of 64mb of RAM, ideally it should be 128mb. That could be another problem.

One way you can install it if, autorun is not working cortrectly, is to put the disk in the CD-ROM drive and don't let it autorun. Then go to Windows Explorer and click on the prog that shows in the CD-ROM drive. NOT the plus sign. Look for the set-up icon and start it from there. If it doesn't start, I am afraid you might have insufficient 'umph in your pooter. It happens.
