Yes, ASPVersionSwitcher is a 3rd party tool. From what I can tell, it simply formats and executes the correct aspnet_iisreg -s
or -sn command to switch a web site from version 1.0 to/from 1.1 of the framework.
The important thing to see in my first post is that aspnet_iisreg from the version 1.0 directory would not run. The problem is
that I need to understand the steps involved in getting version 1.0 of the framework installed and operational on a system (XP or
2003 server) that already has version 1.1 installed.
My final goal is to produce web pages with code behind that will correctly run on a 2000 server that has only version 1.0
installed and that I can NOT get version 1.1 installed onto.
I have spent several hours chasing deadends on the whole version 1.0 vs 1.1 issue. I don't know that I really understand all the
issues etc. I found a KB article (don't have the number at this point) that gave some steps for using (for lack of a better word)
both 1.0 and 1.1 on the same system. It was not really relevant because my version 1.0 aspnet_iisreg would not work at all, so it
should be obvious that I can not switch a web server from one to the other.
I realize that some of this issue may be better served in the aspnet newsgroup, but it also appears that I have basic issues with
trying to install version 1.0 of the framework.
I don't have access to the systems in question at this point to get the exception info. Just some guidance on how to install
version 1.0 after 1.1 is what I was really looking for.
Thanks
Hi,
We are able to install .NET Framework 1.0 after 1.1, because of the
side-by-side execution of .NET Framework. Please refer to the following
MSDN article which states: "The two .NET Framework versions can be
installed in any order."
Installing Multiple Versions of the .NET Framework

Hope this helps.

You can certainly run both versions of the Framework together. However, I'd
like to remind you that the installation of a new Framework version on your
systems is a good excuse to test everything.
Although a Framework upgrade is meant to be transparent to most
applications, I have seen various issues with applications in a production
environment to which the Framework 1.1 was added. These can be caught by
thorough testing. However, don't expect that this upgrade will be pain-free.

To answer your question, if this is resolved. No really.
No one has yet to explain how I can write a program that will run on a system that has only 1.0 installed.
Yes, I understand about the side-by-side etc, but that does not answer the question.
On the other hand, I think we are switch hosting services to someone that has 1.1 installed so, it really does not matter anymore.

Hi Roy,
Thanks for your response. You can configure your application to be executed
in a specific .NET Framwork version as per the article below:
Side-by-Side Execution of the .NET Framework

ml/sidexsidenet.asp
In addition, please also kindly note that there are some backwards breaking
changes from version 1.0 to 1.1:
