I have the same problem.
I have .net 1.1, 1.1 hotfix and 2.0 installed.
I do not have a beta version of .net 3 installed.
I have Norton Anti-virus 2007 and Comodo firewall installed. I disabled both
of them but was still unable to install .net 3.

I am very interested in in solutions to this problem.

I had the same problem, never had any beta version onboard, I also tried
installing via the dotnetfx3 redistributable without success. I found a
workaround - worked for me anyway.
1. Uninstalled .NET 2.0 and 1.1 with its hotfix.
2. Ran MS update custom and selected to install .NET 1.1, 2.0 and 3.0 at the
same time.
3. Ran MS update 2nd time to install .NET 1.1 SP1 and the security updates
for 2.0 (KB917283,KB922770).
4. Ran MS update 3rd time to install .NET 1.1 security update (KB886903)
Hope it helps the rest, at least untill the glitch is fixed.

I fixed it the right way.
I did a google search on the error message and found a link to a Microsoft
article.
A key was missing from my registry. When I recreated it Microsoft Update
installed .net 3 correctly.
