Another IE11 Update failure - Error Code 9C48
I have a new laptop running Win7 Pro SP1 64-bit as its operating system. It came with IE8. I've been applying the dozens of Windows updates that keep showing up, and they all seemed to apply successfuly until I reached the IE11 update/upgrade. That's when things got weird.
-It kept saying that it had failed, with an error code of 9C48.
-If I restarted, it tried to reinstall the update (which failed) and then when I would re-run Windows Update it would show the IE11 update as an important pending update to be applied.
-However, when I would launch IE and check the "About IE" info, it showed that I was running IE11 not IE8. It was as if it was sort of installed but not fully.
Through internet searching, I stumbled on a couple of your threads. I hadn't read the warning about "don't try acting on advice given to another user" yet so I tried some of the suggestions as follows:
- I installed and ran the System Update Readiness Tool. The CheckSUR and CheckSURpersist logs both show "no errors detected."
-I ran System File Checker (sfc /scannow) and the result was that "Windows Resource Protection did not find any integrity violations." (If I had known about "verify only" I would have run that, but this was my first exposure to this tool.)
-I doublechecked a list of IE11 update prerequisites, and it looked to me as though all the required updates were installed.
Here's where I got brave (or foolhardy?):
-When I scanned some of my logs, I found some comments about "newer version already installed."
-I followed the instructions for manually uninstalling IE11 that I found on the MSDN blog site, through a link I found in your 25 Oct 2014 thread on this error.
-I also made sure to change my Windows Update settings so no updates would try to auto install.
-I overlooked and therefore did NOT do the additional step recommended in your October thread, the one that reads as follows:
"Start an Elevated Command Prompt:
Type in, pressing enter after each line:
cd "%userprofile%\Desktop"
IE11Update.exe /update-no
Allow the installation to complete. Restart your computer when done."
Current status:
-My version of IE is back to being IE8 and it appears to be working normally.
-Windows Update is offering me downloads for IE9 and IE10 (as "important"), and IE11 (as "optional). I have not applied any of these updates.
-I have applied all other Windows updates offered to date, but I check first to see what they are.
I need to know what I should do next - the appropriate steps and their sequence.
-do I need to do the last step from the October thread (described above)?
-do I have to install IE9 and then IE10 before installing IE11?
-what else do I need to do?
I want to get Windows and IE settled down so I can proceed with installing other programs as I migrate from my old laptop. The machine came with the OS preinstalled and so far all I've added are Norton and Firefox.
Thanks!
