the reset fixes this problem, but it doesn't help me with the installation.
i am a vs2003 user, so i had .net 1.1 and .net 1.1. sdk installed in my system.
i removed EVERYTHING what has something common with visual studio- previous beta version of 2005, .net 2.0, .net2.0 sdk. even after the removal of .net 1.1 and .net 1.1. sdk nothing changes. the setup still dies at 2/3 of the progress bar.

A reboot should clear this up.
