Yesterday I started a system reinstall (XP meltdown while trying to install SW2008 alongside 2009 and 2010) and started with a prior image of a clean XP installation.  Everything seems to be working fine except for SW2009, it has taken over 12 hours to install (installing straight of the disc) and still has only reached 76%.

What would possibly cause this?  Other than XP and dell drivers, solidworks is pretty much all that is installed.  I have used this xp install image before without problems.
