Do you have .Net Framework 1.0 on your system? If so, do a repair as listed
in the troubleshooter link I gave earlier. Once you've done the repair, try
reinstalling 1.1 version.
Repair the .NET Framework 1.0 by using the command prompt
To repair the .NET Framework 1.0 by using the command prompt, follow these
steps:
1. Locate the Dotnetfx.exe file that you used to install the .NET Framework
1.0. To do this, use one of the following methods: • If you installed the
..NET Framework 1.0 from a CD or from a DVD, insert the installation disc in
your CD-ROM or DVD-ROM drive.
• If you installed the .NET Framework 1.0 from your hard disk, download the
..NET Framework 1.0 Setup program to your hard disk.
• If you installed the .NET Framework 1.0 from a network drive, reconnect to
the network drive.
2. Click Start, and then click Run.
3. In the Open text box, type cmd, and then click OK.
4. At the command prompt, run the following command:
%InstallationPath%\dotnetfx.exe /t:%temp% /c:"msiexec.exe /fvecms
%temp%\netfx.msi"
Note %InstallationPath% is a placeholder for the path of the Dotnetfx.exe
file that you located in step 1.

There are currently three released versions of the .NET Framework:• The .NET
Framework 3.0
• The .NET Framework 2.0
• The .NET Framework 1.1
Service Pack 1 (SP1) is the latest service pack.
• The .NET Framework 1.0
Service Pack 3 (SP3) is the latest service pack.
You may have several versions of the .NET Framework installed on your
computer. Each version of the .NET Framework can co-exist with the other
versions on the computer.
Note Most of the time, you can use the latest version of the .NET Framework
to run applications that were created by using earlier versions of the .NET
Framework.
Note Before you install a release version of the .NET Framework, you must
remove any beta versions on which the release version is based. If you do not
do this, the installation of the release version of the .NET Framework will
fail. You can uninstall beta versions of the .NET Framework by using the Add
or Remove Programs tool in Control Panel. This is a good first step to try if
the installation of the .NET Framework fails from the Microsoft Update Web
site and you need to troubleshoot the issue.
