How to repair .NET

[Robert Schuldenfrei]

Hi NG,

I tried to install an old VS 2005 beta on my machine. Not only did it not
install, but it seems to have installed an earlier version of .NET on my
Vista Ultimate system. Now programs like OneCare are failing with CLR
error: 80004005. From reading KB I understand that Vista uses .NET 3.0 and
I probably over wrote that with 2.0 or even earlier. KB 306160 explains how
to repair an existing installation of the .NET Framework. So far so good.
However, it wants to execute D:\dotnetframework\dotnetfx.exe where D: is my
DVD drive. I have looked at the folders on my Vista SP1 DVD and there is no
top level folder called: dotnetframework. There is a program:
D:\upgrade\netfx\netfxupdate.exe, but I fear that is the Vista installation
routine.

How should I: 1/ Remove .NET from my machine and 2/ Reinstall .NET 3.0?

TIA,

Bob

Just FYI, VS2005 isn't compatible with Vista, you should have gotten a
compatibility warning when you tried to install it. As for your framework
problems, .NET 3.0 and 3.5 are both extensions of the 2.0 framework. The
only thing I can come up with is you installed a beta copy of the .NET 2.0
framework which is causing your problems. If it was me, I'd uninstall all of
the frameworks and download copies from microsoft and reinstall them.

There are links at the bottom of the page for 2.0, 3.0, and 3.5 you can use
to fix your machine.
