I could be that your Windows installer has been corrupted. Try this:- Put your WinXP disc in, then go Start > Run > type in ( or copy and paste this ) sfc /scannow, then okay it. There is a space between sfc and / . This should repair any corrupt files for you. After this has completed, run a Windows Update which may get you version 2 installer. If this fails, do a WinXP repair as follows:
Configure your computer to start from the CD-ROM drive.
Insert WinXP CD, restart computer.
When the Press any key to boot from CD message is displayed on your screen, press a key to start your computer from the Windows XP CD.
Press ENTER when you see the message To setup Windows XP now, and then press ENTER displayed on the Welcome to Setup screen. Do not choose the option to press R to use the Recovery Console.
In the Windows XP Licensing Agreement, press F8 to agree to the license agreement. Make sure that your current installation of Windows XP is selected in the box, and then press R to repair Windows XP.
Follow the instructions on the screen to complete Setup. This will repair your entire WinXP setup, leaving your existing programmes in place. Regards JoeC
