.net framework 1.1 redistributable freezes up during set-up

I am trying to download the .net framework 1.1 service pack and each time it begins Set Up "Registering ASP.net" it completely freezes up. I try to cancel the download and it won't do anything. I actually have to re-boot the computer. I need this in order to download my Quickbooks CD on this computer. I do have .net framework 1.0 and 2.0 on the system. Any ideas?

Hi,
Go to Add or Remove Programs and delete old .Net Framework. You should install 2.0 version of .Net Framework from link HERE
