Hi, welcome to the forums
Your problem is usually to do with a corrupt file, here are a number of solutions which should help your problem.
SOLUTION 1
You need to re-install these files from your ORIGINAL Windows XP CD-ROM. To do this:
1. Insert the Windows XP CD in your CD-ROM drive.
2. Click Start, and then click Run.
3. In the Open box, type cmd, and then click OK.
4. At the command prompt, type the following commands, pressing ENTER after each command:
Quote:
expand CD-ROM "Drive Letter":\i386\config.nt_ c:\windows\system32\config.nt
expand CD-ROM "Drive Letter":\i386\autoexec.nt_ c:\windows\system32\autoexec.nt
expand CD-ROM "Drive Letter":\i386\command.co_ c:\windows\system32\command.com
exit
5. Restart you PC and try installing and running the game again.
SOLUTION 2
Go to the C:\Windows\Repair folder and copy the autoexec.nt file from there to the C:\Windows\System32 folder.
SOLUTION 3

Please note i have not tried this file myself so i dont know how well it work or any problems with it, my advice before trying any of the above is to create a restore point in case you run into any problems.
Hope this helps, let me know how you get on.
Thanks
