.Net Framework 3.0 Setup Error

I ran MS Baseline Security Analyzer 2.0.1 and it said I needed to load .Net
Framework 2.0 and 3.0. I was able to install 2.0. There was an older version
of 3.0 which I uninstalled. I restarted the computer and I attempted to
install 3.0. However, I got "an error occured during setup...". The error
seemed to occure early in the installation. Checking the documentation did
not seem to give me any answer to correcting the problem. Has anyone run into
this problem?

This issue can be caused by a damaged .NET Framework 2.0 installation. In
order to resolve the issue, we have to remove/reinstall previous versions of
..NET Framework. Based on its current status, I suggest trying the following
troubleshooting steps.

Step 1: Download Microsoft Windows Installer Cleanup Utility
=============================================
1. Please visit:
http://download.microsoft.com/downlo...BD/msicuu2.exe
2. Save the file on your Desktop
3. Double click the file msicuu2.exe on the Desktop to install this tool on
the computer.

Step 2: Remove the previous version of .NET Framework 2.0 if installed.
================================================== ===
1. Click Start -> (All) Programs->Windows Installer Clean Up.
2. Please locate and remove all .NET Framework products.

After removing .NET Framework components, let's reinstall .NET Framework 3.0
and its updates.

Step 3: Manually downloading and installing Microsoft .NET Framework 3.0
================================================== =====
1. Click the following link:

Microsoft .NET Framework 3.0
http://go.microsoft.com/fwlink/?LinkID=70848

2. When the file download window appears, please click "Save", and follow
the directions to save it on the Desktop. After downloading the Microsoft
..NET Framework 3.0 setup file on your Desktop, double-click to manually
install it.

3. After completing the above steps, please restart the computer and install
the updates for .NET Framework 3.0 from the following links:
