Updating 1.0 to 1.1

[Jeff Gottesfeld]

I am trying to update .NET Framework from 1.0 to 1.1. The problem is that
any attempt to run the updater fails. I tried to download the updater and
run it locally and it still fails. Is this knowledge article,
http://support.microsoft.com/kb/824643/, valid for 1.0 to 1.1 installation
issues?
Thank

Do you "Upgrade" your .NET app or simple the .NET framework? Strictly
speaking, there is not way to "UPGRADE" .NET framework from older version to
newer version, that is, newer one DOES NOT upgrade older one. They designed
to coexist side by side. You simply INSTALL a new version when it is
available and when you need it. Installing new version does not affect
existing older version. You can run .NET apps wriiten for both versions on
the same machine.

With that said, you may not need to keep older version of .NET framework, or
if you get a new computer, you may only have latest version of .NET
framework installed. In this case, your app written with older version of
..NET framework most likely would work fine. However, the app on older
version of .NET may have used certain feature of older verion of .NET, which
for some reason would not be available anymore, then the app would break on
latest .NET version machine. Such thing would occur very rarely, but no
guarantee it would never happen after many versions of .NET framework
released.

Norman,

No they are only designed to be side by side in a development environment
where all visual studio's are installed.

In a normal user environment the latest framework should cover all. Due some
problems that is not as it should be, so we are all waiting on the updates
for those failures.

But let us not make from these bugs a standard and tell that there should
standard (beside develepmont computers with more versions) be more
frameworks installed on a user computer.
