The .NET Framework is required by a large selection of Windows software, making Windows software easier to develop for and more uniform. However, each program may look for a specific version and display an error if you don't have it. Thus, the best approach is to install the latest version, then install each older version a program requests if the latest version is insufficient. You can uninstall the older versions if you want, but those older programs may stop working until you reinstall the older version of .NET Framework.
Hope this helps,

The other day, I saw Windows Fix It Center mentioned on CNET and thought I'd give it a try. After downloading, I was told I needed Microsoft .NET Framework 2.0 so followed the link to download this. When I'd done that, went back to install Fix It Center to be told again I needed Microsoft .NET Framework 2.0. I went through the same procedure in case I'd done anything wrong but got the same message. I'm now getting an update message saying I need Microsoft .NET Framework 3.5 Service Pack 1 and when I tried to install this, it failed to install. It hasn't slowed down my computer, but I want to get rid of that annoying update shield in the task bar! I already have Microsoft .NET Framework 1.1, Microsoft .NET Compact Framework 2.0 SP2 and Microsoft .NET Framework 2.0 SP2 on my computer but I'm wary of deleting the .Net Framework 2.0 installations in case this causes any damage. My computer is an HP Media Center PC running on Windows XP. Are these updates to Microsoft .NET Framework really needed as my computer seems to be running normally anyway?
