I tried to download .NET Framework 2.0 via 'Automatic Updates'. It seemed to download OK, but it failed to install properly. From 'Add or Remove Programs' in 'Control Panel' I tried to carry out a repair of the installation. This lead to a dialogue box which said there was an error during set-up and gave a link which lead to site

Steps to repair the .NET Framework installation
1. Obtain the original installation source. For example, if you installed the .NET Framework from a CD-ROM or from a DVD, insert that disc. If you downloaded the .NET Framework , download the .NET Framework again. Make sure that you click save to disk. If you installed the .NET Framework from a network share, reconnect to that share.
2. Click Start, click Run, type the following command, and then click OK:
N:\dotnetframework\dotnetfx.exe /t:c:\temp /c:"msiexec.exe /i c:\temp\netfx.msi REINSTALL=ALL ReinstallMODE=vomus"
Note Replace N:\ in this command syntax with the original installation path.

Important If you do not have a C:\temp folder on your computer, create one before you run this command.
The Microsoft Windows Installer will verify and repair the .NET Framework installation.

APPLIES TO
• Microsoft .NET Framework 2.0
• Microsoft .NET Framework 1.1
• Microsoft .NET Framework 1.0

I should be very grateful for advice. Is the above the solution the one I should be pursuing? And what does "Important If you do not have a C:\temp folder on your computer, create one before you run this command." mean - how do I find out if I have a C:\temp folder, and how do I create one if I do not? Also, from where can I download .NET Framework 2.0 to disc?

I have tried to uninstall the .NET Framework 2.0, but was again presented with a dialogue box saying there was an error during set up.

Further, 'Automatic Updates' keeps trying to install a Service Pack for .NET Framework 2.0. It seems to download OK but will not install.

As I say, I would be very grateful for advice for, as can be seen from my questions, I am fumbling round in the dark!!! I am running Xp Home.
