Code 9C48 - Windows update trying to install IE9 when it is already installed.

As of today when I try to install new systems (HP Notebooks)  and I run all the updates I get Error 9C48 on trying to install IE 9.    IE 9 is already installed and is shown in the update list as successful.    I see that this is happening all of the sudden today for many people.

Has anybody experienced this and found a solution?

OK here is the solution.  I got this of another website and credit goes to Jonathan Sahagun.

Instructions:
 1.Uninstall IE9, if you already have it installed, and restart the computer.
2.Download the installer.
3.Disconnect from the internet. This is important because the installer attempts to download the latest, bad binaries from Windows Update.
4.Let the install finish, and restart.
5.Reconnect to the internet and check Windows Update. If all went well, you should be able to see the Cumulative Update for IE9, instead of IE9 itself.
 
Again, the key is to install without any internet connection, to prevent the installer from fetching the latest and bad binaries.


I have done this on 3 machines and they are all working now!

**This is only for the updating problem that started on April 11, 2012

When I have heard of this happening in the past, it is typically related to something with the registry.  Has anyone made any registry-related modifications on those machines?

That being said, there are a few things you can try to potentially alleviate the problem.  Microsoft has automatic "Fix It" utilities for both Internet Explorer and Windows Update:

If those don't fix the problem, there is a Windows update readiness tool that you can run.  Ensure that you use the one that applies to that particular version of Windows 7 (either 32 or 64-bit):

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Have you checked to see if there is a System Restore point you can utilize in an attempt to drop back to a stable snapshot of the operating system?

Glad to hear that you found a viable solution.

Very interesting, though.  IE9 was officially release 13 months ago, and this is the first time that I have heard of a problem quite like this.  There must be something related to certain pre-installed configurations that is a contributing factor.  If it was strictly caused by something within the monthly Windows Updates from April, there would be countless complaints on the Internet from everyone who already has IE9 installed.  Needless to say, that's not the case.

Here actually had been many complaints.  Not only for Windows 7 but Windows Server 2008 and only after April 11.    You would only notice the problem if you were installing the optional updates as IE 9 works just fine.

Here is the other thread I was following

Oh and thank you for trying to help out!!   I do appreciate it.
