What version of XP are you using?

i am using windows xp professional edition

is there a chance that it would work that time?

If you're not, you need to be an administrator on the computer when you install IIS. If you have multiple users on your machine your login may not be an administrator.

If that's the case, uninstall IIS, reboot, login as administrator, then reinstall IIS.

If you're running any script blocking software or firewall software, try turning them off before you install.
