2 hours to Install 2009!?!

Just installed 2009 from the DVD and it took 2 hours toinstall, whereas 2008 from DVD was about 20mins (6 times shorter!),has anyone else noticed this problem?
I have a sneaking suspicion the software isn't going to be sixtimes better....
My system is well within spec, even has a Solidworks recommendedgraphics card.
As you can imagine I'm not a happy bunny, those two long fraughthours i can never get back!SolidworksAdministration
