I ran the tool. It wanted to start and restart and also fix the windows installer service. It completed successfully and then I reran the update. Still get the same failed message and it sent some logs to Microsoft. Any other ideas?

Hi, I have not the permission to access the log file on your SkyDrive. I suggest you remove .NET Framework 4.0 components. Manually download the standalone installer for .NET Framework 4.0 from the website and install it in Clean Boot mode to check the result.

I can't get any updates for .net framework 4.0 to install. I have tried uninstalling and reinstalling .net framework 4.0 but I still get failed error messages. Error code: 0x80070643. I've tried everything in this article: http://support.microsoft.com/kb/976982

You should use .NET Framework removal from Aaron Stebner's blog and reinstall .NET Framework. This is known issue. Rgds Milos
