Can you Remove earlier versions of Net.Framework

[Gary]

I currently have Microsoft. Net Framework 3.5 Sp 1 downloaded. Question I
have is can I remove all previous versions of Framework 1.1, 1.1 Hotfix, 2.0
Service Pack 2, and 3.0 Service Pack 2 or do I have to keep any of these
versions for Net Framework to work properly?
Thanks

You have to keep 2 for 3 to work. You have to keep all that your programs
require.

Can you? Yes. Should you? No.

Do I need still need older versions of the .NET Framework on my system after
installing .NET Framework 3.5 SP1?

Don't know - cannot say. You may have things installed that use the other
versions of the .NET Framework. They are not cumulative. Better if you
leave well enough alone.

If you have an application that uses/needs .NET 1.1 then 2.0 and 3.0 are not
to be considered supersets or replacements for .NET 1.x
So if you where to delete version 1.1 then there is a good chance
the application that requires .NET 1.1 will fail. The same is true for later
versions.

Each version of .NET is usually installed along with the application that
requires it, so if you have all three or four versions, then chances are
that somewhere along the way you installed at a minimum 3
applications, with each of those 3 applications requiring and installing
it's own version of .NET

How to determine which versions of the .NET Framework are
installed and whether service packs have been applied:

As for .Net 1.0 not being listed in Add/Remove Programs

For a list of each version of .NET and where to download:

Scroll down to method #1, step 4 for the download links

The thing is that the naming scheme is rather misleading. We're used to
Office 11 superceding Office 10 and Office 97, and you can only have one
version of Office installed.

But these .Net Frameworks aren't like that at all, they are not the same
library or set of apps updated. They are distinct and different versions.

If you have utiltiies or apps that call for a specific version of .Net
Framework (such as a video driver control panel), you need *that* version.
The others, including later ones, won't do the job.

Hi Gary,

What everyone is saying is, if a program you have installed needs a
specific version of .NET, then that version needs to be installed. But
many programs run on version 1 and MS offers updates with 2, 3, 3.5,
etc. But you may not need any of those. You need to know what your
programs require. You may not need the additional bloat of all the
newer versions, just because you have an early version installed.
