Microsoft .NET Framework 2.0 Service Pack 1 (KB110806) failed
Last year Microsoft released their Service Pack 1 for Microsoft .NET Framework 2.0 (KB110806). For some reason the Service Pack 1 did not install and generated a lot of error messages in the system eventlog or displays the illustrated screenshot below. In my case the SP1 update failed and the Windows Update Agent (Automatic updates) retried to reinstall constantly; because the failed the production Microsoft SQL Server 2005 server failed to start the “SQL Server Agent” service which is depending on the .NET Framework many of the scheduled jobs failed to run.

Screenshot 1 – Automatic Updates – Microsoft .NET Framework 2.0 Service Pack 1 (KB110806) were not installed.
This behavior may also occur with:
- Autodesk Autocad 2008
- Quickbooks 2008
- Backup Exec
- Any other application depending on .NET Framework
If you are a novice user than read my “User guide” below how to remove the failed installation of Microsoft .NET Framework 2.0 Service Pack 1 (KB110806) with “Windows Installer CleanUp Utility”.
I start to troubleshoot and hopefully these steps will help you fixing your installations.
Check the Windows Eventviewer System

Event reported at 12/27/2007 7:42 AM:
Installation Failure: Windows failed to install the following update with error 0×80070643: Microsoft .NET Framework 2.0 Service Pack 1 (KB110806).
I tried to remove KB928365 security update manually.

Than I tried to uninstall Microsoft .NET Framework 2.0

Setup end with problem encountered.

So I ended up with corrupt installation of .NET Framework 2.0 and SQL agent was not running. SQL server 2005 run fine.
I googled and found couple of threads at Microsoft newsgroup suggesting to uninstall the installation using a tool “Windows Installer Clean Up”.
I download the bits from http://support.microsoft.com/kb/290301 and installed msicuu2.exe. From Start Menu I run Windows Installer Clean Up shortcut and selected (All Users) Microsoft .NET Framework 2.0 and removed it.

I went back to the Automatic Updates client directory C:\WINDOWS\SoftwareDistribution\Download\Install and rerun NetFx20SP1_x86.exe which now was successful.

The combination of KB928365 and KB110806 resulted in a failed deployment.If this post helped you please support me by clicking on the Google Ads below and let others also be helped by reading this blog. I am already exceeding my monthly bandwidth quota.

Works like a champ. One other thing is, that I was able to click on the update icon near the clock, (because it didn’t go away after the fix) and the update installed. Before the fix Quickbooks would not work, after the fix Quickbooks was working fine again……THANKS

I had to manually stop the IIS Admin service before attempting to install in order to get it to install without errors…
