R – Installing ASP.Net Framework 3.5 on Server (From 2.0)

asp.net-3.5frameworksinstallation

I want to upgrade the Windows 2003 x86 server which is running ASP.NET 2.0, to support ASP.NET 3.5

Which file / files do I need?

Do I need to install 3.0 first, then 3.5, then 3.5 SP1, or will the full download of 3.5 SP1 (dotnetfx35.exe 3.5.30729.1, 231 MB) do everything?

Also, I believe I have to install the following at the end of the process:
NDP20SP2-KB958481-x86.exe,
NDP20SP2-KB958483-x86.exe,
NDP20SP2-KB958484-x86.exe

Will anything interfere with live applications currently running?

Thanks

Installing 3.5 SP1 by itself will add everything you need. I don't think live applications will be interrupted, but performance might be impacted while the installer is running. Be sure to run Microsoft Update after as well for any post SP1 updates that might be needed.
