Deployment Question Regarding .Net Framework 3.5 Service Pack 1 Full Install

Question

When you install .Net Framework 3.5 Service Pack 1 (full install) onto a server that has an older version of .Net Framework installed (such as, .Net Framework 2.0 only), will the existing installation be overwritten?

Answer 2

If you use the full cumulative update to .NET Framework 3.5 SP1 on a system with .NET Framework 2.0, it is possible that some 2.0 components will be replaced with updated components.

Here's why: .NET Framework 3.0 is an extension of 2.0, not a full framework. The standalone cumulative installer for 3.5 SP1 contains all components needed to install or update (as required) .NET Framework 2.0 (the base framework) and its extensions, .NET Framework 3.0 and 3.5 along with all published updates (Service Packs, etc.) to 2.0. 3.0 and 3.5 to bring it up to 3.5 SP1.

The full, cumulative installer is here:

If you have any further questions, please ask.

Dumb question::  Do I need to uninstall Ver 1.1 before installing v3.5??   (I have a program which requires V2.0 and my WinXP system has only ver 1.1 installed!)  Yes I am a very green newbie at this !!

Answer 4

Hi, navi8or.

No you do not need to remove .NET Framework 1.1 before installing 3.5. The two .NET Frameworks are separate and independent of each other.

Please be sure to use the cumulative installer I linked in my previous reply:
