Answer 1

Perform windows update from update.microsoft.com

later, try installing .net framework in the machine. This will usually fix the problem.

Hi Mgringle,

Welcome to MSDN forums. And thank you for your post.

Some clarification with you:
What's your OS?

Based on your description, it seems that you have some concern on .NET Framework 3.5 installation, right?

If you're running Windows 7 on your machine, .NET Framework 3.5 with SP1 is shipped with it as one of OS component.
For .NET Framework 3.5 with SP1, it includes .NET 2.0 with SP2 and .NET 3.0 with SP2 as prerequisite.
This means, you have the .NET Framework 2.0 SP2, 3.0 SP2 and 3.5 SP1 plus a few post 3.5 SP1 bug fixes on Windows 7. They are OS components. .NET 3.0 SP2 and 3.5 SP1 can be added or removed via the Programs and Features control panel. Thus, we don't need to manually install them. You can try Verifictaion Tool to verify .NET Frameworks on your machine.

If you're running XP or Windows Server 2003, could you please try the following points for further troubleshooting?
1. Download .NET Framework 3.5 full package
2. Use Cleanup tool to remove .NET Framework 3.5 >> 3.0 >> 2.0 in order
3. Run the installer to install .NET 3.5
4. If any problem occurs during the installation, use Collect tool to collect the log files for further troubleshooting.
(Please follow the following steps to collect the log files)

If you're running Vista or Windows Server 2008:
1. Download .NET Framework 3.5 full package
2. Check whether you have turned on the windows feature of .NET Framework 3.0.
Please go to Control Panel -> Programs and Features -> Turn Windows features on or off -> Check the box next to Microsoft .NET Framework 3.0.
3. Use Verification Tool to verify .Net Framework 2.0, 3.0. If .Net Framework 2.0 and 3.0 cannot be verified on your computer, you can try to follow the steps mentioned in the following blog to repair the .NET Framework 2.0 and 3.0 on Windows Vista.
See: http://blogs.msdn.com/astebner/archive/2007/03/26/how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx
4. If .NET Framework 2.0 and 3.0 are verified successfully but the installation still fails, please collect the log file.
(Please follow the following steps to collect the log files)

The steps to collect the log:
- Try to clean your "%temp%" folder (Start Menu >> Run >> Type "%temp%")
- Install .NET Framework 3.5 full package
- Collect the logs from "%temp%" folder
