Microsoft .NET Framework 2.0 Service Pack 1 (KB110806) failed

Microsoft released their Service Pack 1 for Microsoft .NET Framework 2.0 (KB110806) which was available for install through Automatic Updates. For some reason the Service Pack 1 did not install on my Windows 2003 Server. The update generated several error messages in the system event log.

In my specific case the SP1 update failed and the Windows Update Agent (Automatic updates) tried to reinstall the update over and over. The failed updated caused that “SQL Server Agent” service (Microsoft SQL Server 2005 Server) failed to start. The service was depending on the .NET Framework and all scheduled jobs failed to run on the SQL server.

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

I dealt with this issue and by documenting my steps I hope it will help you fixing your failed .net update installations.

Check Windows Event Viewer System log

Event Type: Error
Event Source: Windows Update Agent
Event Category: Installation
Event ID: 20
Date: 12/20/2007
Time: 7:18:58 AM
User: N/A
Computer:
Description: Installation Failure: Windows failed to install the following update with error 0x80070643: Microsoft .NET Framework 2.0 Service Pack 1 (KB110806).

When checking error messages in the WSUS Update Services console I found following event:

Microsoft .NET Framework 2.0 Service Pack 1 (KB110806)
Event reported at 12/27/2007 7:42 AM:
Installation Failure: Windows failed to install the following update with error 0x80070643: Microsoft .NET Framework 2.0 Service Pack 1 (KB110806).

I tried to remove KB928365 security update manually.

I got a warning when I tried to remove KB928365 manually.

Windows Installer: This patch package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this a valid Windows Installer patch package.

My last option was to uninstall Microsoft .NET Framework 2.0

Setup stopped with a encountered problem.

Microsoft .NET Framework 2.0 has encountered a problem during setup. Setup did not complete correctly.

So I ended with a failed installation of .NET Framework 2.0 and the SQL Server agent was not running. SQL server 2005 was still working.

I googled and I found couple of threads at Microsoft newsgroups suggesting to uninstall the installation using a tool “Windows Installer Clean Up”.

~~I created the following “User guide” how to remove the failed installation of Microsoft .NET Framework 2.0 Service Pack 1 (KB110806) using the “Windows Installer CleanUp Utility”.~~

I download the utility from http://support.microsoft.com/kb/290301 and installed msicuu2.exe. From Start Menu, I run Windows Installer Clean Up shortcut , selected (All Users) Microsoft .NET Framework 2.0 and removed it.

I reinstalled .Net Framework 2.0 again, I went back to the Automatic Updates client directory C:\WINDOWS\SoftwareDistribution\Download\Install and rerun NetFx20SP1_x86.exe. The installation was successful now.

The combination of KB928365 and KB110806 resulted in a failed deployment. It took me some time to research, remove and reinstall the framework but in the end the output was satisfying. The utility can be used to remove any MSI based installation and this particular case I used it to remove the .Net Framework suite.

Thank you. When my accounting program would not load or re-install and the 2.0 service pack would not install, I thought I was going to have to spend hours with tech support getting it figured out. You are a life saver.

I was able to resolve the same issue by going to add/remove programs and instead of uninstalling NET 2.0, I ran the repair option (rather than the unistall option). I restarted the computer with Automatic updates OFF, then switched on Automatic updates and restarted the computer again. The KB 110806 update then installed successfully and I restarted the OS once more to complete the update. (Win XP SP2).

Unistalling the NET 2.0 would seem to be the safest option, but repairing it may work if you are looking for a quick fix.

My issue might have been exactly the same as Phil’s: QuickBooks 2008 suddenly stopped working at the same time as Microsoft Automatic Updates tried and failed to install the .NET Framework 2.0 SP1. Of course, trying to uninstall the .NET Framework wouldn’t work, either, nor did System Restore. I was about to waste an entire day wiping our accounting machine clean and reinstalling the OS…

This tip solved the problem and saved me a bundle of time and hassle. Thanks!

I just downloaded the Windows Installer Cleanup porgram (msicuu2.exe). After I openend it and located the offending Microsoft .Net Framework 2.0 and removed it, my problems were over. The Micrsoft .Net Framework 2.0 Service Pack 1 was waiting for me in the update shield at the bottom of the screen as it had for the past month or so. I clicked on “intall” and it finally loaded. Hurray! And it all seemed so complicated when Microsoft explained it. Thanks for your help.

Thanks for all this work and detailed, easy to follow support!! I got the .NET SP1 uninstalled just fine and followed the directions to reinstall. Reinstall from the Windows path shown (D:\Windows\SoftwareDistribution\Download\Install\NetFX20SP1_x86.exe still failed – it appears that a ‘base’ reinstall of .NET 2.0 is required before installing the SP1 patch (?)

I have been trying to get my computer to install service pack 3 for two weeks with no success. I noticed that the Microsoft.NET framework service pack 2 and service pack 3 were always trying to install, but for some reason could not. I have been in touch with Microsoft and spent weeks trying to fix the problem to install SP3. The Microsoft representative tried everything, but I was unable to install SP3. I even mentioned to him about the problem with Microsoft.NET install, but he didn’t seem to think this was a problem.

You solution worked. Thank you!
