NET Framework 1.1 will not install on my computer

I have tried everything I can think of - several programs I am trying to install require NET Framework to run. When I try to install it, it tells me that it failed and to contact product support. Since I do not have $99 an hour to pay Microsoft, I need to find the answer myself. I downloaded the newest copy from Microsoft, and even installed NET framework 2 but nothing helps. My machine does not show it as installed. Can someone help me? Thanks.

I have all the latest updates, at least that is what I am told when I go in to see if there are any updates available. The one you mentioned is for Windows NT Server 4.0 and I have Windows XP Home on this machine. I am confused. Please reply. Thanks.

Sorry I never came back on and told the results. After many attempts, searches, and asking anyone and everyone, I finally got in touch with someone from Microsoft. He worked with me for quite a while until we finally corrected whatever was causing the problem and fixed it. The reason it was important to me was I could not install and use Quickbooks without it. I don't really understand what the problem was so unfortunately I cannot help anyone else. All I can say is keep after it if you have the problem.
