Upgrading NT4 to XP Pro

I’ve tried the installation from an Upgrade CD a couple of times and the installation has fallen down each time – the first time it stopped was after 5% of the ‘Setup is copying files’
whilst copying batmeter.dll. The second time it stopped at 17% on driver.cab.

Is the yellow progress bar and the %age number an accurate gauge? The current attempt has been frozen on 11% (file cdmedia.hlp) for more than
an hour now.

The system has got very little hardware – no peripherals at all. Do you think it may be worth stripping out the sound card, network card and modem? As you can tell, I’m fast running out of ideas!!!
