    i'Ve got the same problem. after the progress bar of the setup program moved to about 2/3 of it, the setup program dies. nothing changes in it's memory usage, and i can't remove it from the task manager- it stays there and uses 50% of my computer performance.
    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.

    Hi Ron,

    A reboot should clear this up.

    Have you tried using the uninstallation tool referenced in the following link

    The preview version(s) of VS2005 maight not have been completely uninstalled.
