Have you interupted the installation in any way? May I highly recommend you update your Installshield install engines. See here: http://consumer.installshield.com/kb.asp?id=Q108158 This link & a no. of others to do with installation problems are listed in the Sticky at the top of this section. I don't suppose you saw those stickies. In other words the problem is not the LW installer but your set up. It's like trying to fit a porsche engine into a mini mina or volkeswagon lol.
