I had 1.5.1. installed and unistalled before trying to load 1.6. The 1.6 install failed so I checked the forum and could see there was a updated version of the install so I downloaded it and tried again. I uninstalled the failed 1.6 and tried the install again and it failed again - as best as I can remember in exactly the same manner as the first install. I took a screen shot of the install progress and errors which is attached.

My system is a 1Gb XP AMD laptop with Visual Team Studio 2005 and SQL Server 2005 Developer Edition. All with the latest service packs.
