KB 928366

As soon as I try to download the up date .net framework 1.1 sp1 (KB928366)
it tries to down load it on top of .net framework 1.1.
The only prompt I get is "do you want to install on top of .net framework
1.1."
with only two buttons either yes or cancell.
I went to window/ Microsoft. net/ framework & create another folder to try
& put kb928366 in there but I can't seem to get that right.
I have done a disk clean up & a defragmentation but that doesn't help as well.
I created a new folder in windows/ microsoft.Net/ Framework but can't seem
To download it in that folder
I am using windows XP home & office 2003 professional.
