Internet Explorer 9 Install Fail

Posted by William Diaz on July 11, 2012


While troubleshooting some bizarre behavior in IE, I decided the only way to fix the problem was to uninstall IE 9 and reinstall it. To remove IE 9, you go to the Program Features > View installed updates and locate the IE 9 install under Microsoft Windows. One reboot later I ran the IE 9 installer and encountered the generic Windows Internet Explorer 9 failure message: “Internet Explorer did not finish installing…”

This can be for any number of reasons, the most of which are covered in this Microsoft KB: Troubleshoot problems when you cannot install Internet Explorer 9. I wasn’t so lucky, however, and was left scratching my head. Maybe the Windows Event Viewer might reveal something more verbose.

The thing you should know about IE 9 is that it is considered an update. As a result, when you install it and it fails, you can find update specific events in the Setup logs. You should see a error under the source of WUSA (Windows Update Stand Alone installer):

The verbose portion of the error is, I admit, cryptic, and I’m still left scratching my head. But this is still better than a generic error message. Perhaps I can get something by just copying the unique bit of the error: “The identities of the manifest are identical but there contents are different.” A search leads me to a different MS product, SQL 2012, but what the hell: FIX: Error message when you install SQL Server 2012: "The identities of the manifests are identical but their contents are different.” I install the recommended update for Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package ATL Security Update. Afterwards, I run the installer for IE 9 again and it installs. Case closed.


UPDATE

So, I have been uninstalling and reinstalling several dysfunctional instances of IE 9. In another case, the reinstall failed with the same generic error first encountered. Looking in the Event > Setup logs did not reveal the same verbose type of error. In fact, the failed install was logged as an Information event: “Package 982861 failed to be changed to the Installed state. Status: 0x80073715.”

Looking up the error status code, we see the same verbose as the WUSA error encountered earlier: “ERROR_SXS_MANIFEST_IDENTITY_SAME_BUT_CONTENTS_DIFFERENT. The identities of the manifests are identical but their contents are different.” The security fix I applied in the first case didn’t help. Instead, I decided to look at any recently installed updates on the workstation. This can be done via Control Panel > Programs > Programs and Features > Installed Updates. I focused on Microsoft Windows updates and found three installed updates after the removal of IE 9.

I suppose this behavior is expected since uninstalling IE 9 rolls back to IE 8. Perhaps one of these updates was throwing off the IE 9 installer. I selected each of the three (it was late and I didn’t want to remove 1, reboot, repeat). After a restart, I ran the installer and it was successful.

Since I’m at it, I also had a couple hiccups trying to uninstall these dysfunctional IE 9 setups. The following error was encountered: “Windows Update. An error has occurred. Not all of the updates were successfully uninstalled.”

A quick fix was to run Microsoft’s Fix It from How to uninstall or remove Internet Explorer 9 when the standard uninstallation process does not work.


Update

I have to admit now there is another random element to what is going on here. I have since been involved in more of these mysterious failed IE reinstalls and the experiences recorded below have not been consistent. Our virus enterprise virus protection may be playing a role in all of this. Examining the virus protection logs shows that one of the IE 9 install processes if being flagged because it might be trying to terminate a virus protection process:

This does not necessarily mean that McAfee is actually preventing the installation, as even with successful installs of IE 9 I still see these logs generating the same report. The odd thing that remains is that an install will fail one moment to the next and then, suddenly work a few minutes or hours later.

    Thanks for this post, i will try that.

    • I neglected to update this post but since running into this several more times. I am suspicious that McAfee might have been involved. After examining desktop protection logs I saw the following entry repeated several times where one of the binaries in the installer was being terminated:

      7/26/2012 10:58:13 AM Blocked by Access Protection rule C:\WINDOWS\TEMP\IE9EA2F.tmp\IE9-support\ienrcore.exe C:\Program Files (x86)\McAfee\VirusScan Enterprise\shstat.exe Common Standard Protection:Prevent termination of McAfee processes Action blocked : Terminate

      I dont know if this is actually what was happening because the odd thing is that even after successful installs, I was still seeing these log entries. Its possible that my stated solution in the post was just luck.
