Hi, this game is a bit old so it may have trouble running on a new operating system such as 7. In addition to elvenleader3's advice, if you have a multi-core processor(2, 3 4 cores) you may have an error as google has informed me that it does not like multi-cores. If you have a multi-core try this..
As soon as the game loads, Ctrl-Alt-Del and go to Task Manager, then processes. Right Click on SPEED2.EXE and select "Set Affinity" Make sure only one processor is checked. It should work, this step will need to be repeated each time. Let me know if it works. Also try running it as administrator and in Winxp3 mode.
Also if you can get the specs of your dad's laptop(specifically your CPU) it would be appreciated. Thanks.
EDIT: Found this patch on CNET, it's not the offical source but CNET is a good clean place for programs. Patch can be found here.
