Yes, deliverd via auto update. Yes I also have all previous versions showing on my pc but I have installed latest version without any problem. There were a few threads about this problem a little while ago, so if you do a search in these forums for .NET ... you will be able to have a read. I don't know why version 1.1 is trying to install when you have the latest version installed. Why not hide it in future from updating via the MS Update ?
