WinXP(home) sp3 and all updates except 1.1 sp1 which won't install. This leads me to a question. Why have the older version of .NET on a system? I have 1.1, 1.1 Hotfix (kb928366), 2.0, 3.0, 3.5, on this system. I have an dup system, same MB, winxp(home), .etc., etc. and it only has 2.0, 3.0, 3.5 so not sure why I need to keep 1.1 or for that matter 2.0 or 3.0... I've read as much as I can relating to .net but can't find an answer. thanks, L.
