I had the same problem. I have Win XP as well. I put the brand new just opened disk in, and it spun and spun, locked up the entire system, had to reboot. Then I came here, read this thread, turned off my McAfee's AV and my Sygate firewall, Put the disk in again, and waited. It took a minute or two or three, but then the install popped up. The install itself took almost ten minutes. A lot of data, but it was moving quickly.
To those still having the problem, I fully recommend you turn off all Anti-virus or firewalls, put the disk in, and wait it out. It's a huge install file, and it takes the system a while to load one that large, even with a good cd rom speed. Most installs aren't that large, they're broken into mini cabs and files.
To the OP, with Win XP on SP1, please upgrade to SP2, and any other updates you lack. Go to
http://windowsupdate.microsoft.com It contains many security fixes that you may not even know you need. I used to have a lot of problems with spyware, pop-ups, websites installing things without me knowing, downloading files, and it was bypassing my firewall and AV protection because of holes in XP. It's like swiss cheese. lol A new hole was patched again on the 9th too. A hole that let a website's trojans be installed. So please, make sure you're fully updated. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
