Hello All. Many times I installed fresh system Windows Server 2008 R2 SP1 from technet ISO. Install all updates, approx 65 updates with IE 9. After reboot I can see that Windows Update shows Windows Internet Explorer in Important Updates again! When I try to install it I get error: Code 9C48. Windows update encountered an unknown error Log is here: 2012-04-12 16:01:59:156 776 f0 AU No featured updates notifications to show 2012-04-12 16:01:59:156 776 f0 AU Successfully wrote event for AU health state:0 2012-04-12 16:01:59:156 1548 4d8 CltUI AU client got new directive = 'Shutdown', serviceId = {9482F4B4-E343-43B6-B170-9A65BC822C77}, return = 0 2012-04-12 16:01:59:156 776 89c AU AU received handle event 2012-04-12 16:02:00:671 776 8b0 Agent * Added update {D8BA5DBF-AADE-4125-BBDF-48DCC5950131}.101 to search result 2012-04-12 16:02:00:671 776 8b0 Agent * Added update {11EDC844-7375-4C9F-9D65-3B9C40C21EA1}.100 to search result 2012-04-12 16:02:00:671 776 8b0 Agent * Found 2 updates and 13 categories in search; evaluated appl. rules of 264 out of 570 deployed entities 2012-04-12 16:02:00:671 776 8b0 Agent ********* 2012-04-12 16:02:00:671 776 8b0 Agent ** END ** Agent: Finding updates [CallerId = AutomaticUpdates] 2012-04-12 16:02:00:671 776 8b0 Agent ************* 2012-04-12 16:02:00:671 776 8b0 Report REPORT EVENT: {FD08FC31-767F-4F99-B59A-91DAF378B368} 2012-04-12 16:01:57:546+0400 1 182 101 {D8BA5DBF-AADE-4125-BBDF-48DCC5950131} 101 80070643 AutomaticUpdates Failure Content Install Installation Failure: Windows failed to install the following update with error 0x80070643: Windows Internet Explorer 9 for Windows Server 2008 R2 for x64-based Systems. 2012-04-12 16:02:00:671 776 8f0 AU >>## RESUMED ## AU: Search for updates [CallId = {4BB6D666-1C53-4CC9-95FA-A1BA307A27A7}] 2012-04-12 16:02:00:671 776 8f0 AU # 2 updates detected 2012-04-12 16:02:00:671 776 8f0 AU ######### 2012-04-12 16:02:00:671 776 8f0 AU ## END ## AU: Search for updates [CallId = {4BB6D666-1C53-4CC9-95FA-A1BA307A27A7}] 2012-04-12 16:02:00:671 776 8f0 AU ############# 2012-04-12 16:02:00:671 776 8f0 AU No featured updates notifications to show 2012-04-12 16:02:00:671 776 8f0 AU Setting AU scheduled install time to 2012-04-12 23:00:00 2012-04-12 16:02:00:671 776 8f0 AU Successfully wrote event for AU health state:0 2012-04-12 16:02:00:671 776 8f0 AU Auto-approving update for download, updateId = {D8BA5DBF-AADE-4125-BBDF-48DCC5950131}.101, ForUx=0, IsOwnerUx=0, HasDeadline=0, IsMinor=0 2012-04-12 16:02:00:671 776 8f0 AU Auto-approved 1 update(s) for download (NOT for Ux) 2012-04-12 16:02:00:671 776 8f0 AU ############# 2012-04-12 16:02:00:671 776 8f0 AU ## START ## AU: Download updates 2012-04-12 16:02:00:671 776 8f0 AU ######### 2012-04-12 16:02:00:671 776 8f0 AU # Approved updates = 1 2012-04-12 16:02:00:671 776 8f0 AU AU initiated download, updateId = {D8BA5DBF-AADE-4125-BBDF-48DCC5950131}.101, callId = {65A13653-518E-4789-BC88-A60286512477} 2012-04-12 16:02:00:671 776 8f0 AU Setting AU scheduled install time to 2012-04-12 23:00:00 2012-04-12 16:02:00:671 776 8f0 AU Successfully wrote event for AU health state:0 2012-04-12 16:02:00:687 776 8f0 AU Successfully wrote event for AU health state:0 2012-04-12 16:02:00:687 776 8f0 AU # Pending download calls = 1 2012-04-12 16:02:00:687 776 8f0 AU <<## SUBMITTED ## AU: Download updates 2012-04-12 16:02:00:687 776 8f0 AU Successfully wrote event for AU health state:0 2012-04-12 16:02:00:687 776 f0 AU Getting featured update notifications. fIncludeDismissed = true 2012-04-12 16:02:00:687 776 f0 AU No featured updates available. 2012-04-12 16:02:00:687 776 f0 AU Getting featured update notifications. fIncludeDismissed = true 2012-04-12 16:02:00:687 776 f0 AU No featured updates available. 2012-04-12 16:02:00:703 776 8b0 Report CWERReporter::HandleEvents - WER report upload completed with status 0x8 2012-04-12 16:02:00:703 776 8b0 Report WER Report sent: 7.5.7601.17514 0x80070643 D8BA5DBF-AADE-4125-BBDF-48DCC5950131 Install 101 Unmanaged 2012-04-12 16:02:00:703 776 8b0 Report CWERReporter finishing event handling.

So, as I see its a problem with Windows Update Servers? MVP | MCP Club lead, Moscow

A bad patch I think, so unapprove them maybe if you use a WSUS until MS fix them.MCP | MCTS 70-236: Exchange Server 2007, Configuring

I seem to have solved the problem on my computer. I am installing Windows 7 Home Premium, but reading through this thread, the symptoms look similar enough. Please let me know if this also works for you. The basic premise seems to be that the IE9 installer that is online in Windows Update and even the IE9 consumer site is bad. So if we try to pull the installer from these online sources after April 10, we would always get a bad copy, whether it's from Windows Update or from a manual installation. You would know you have a bad installation if the version number in the "About Internet Explorer" dialog does not match the version number stored in the iexplore.exe executable. A good installation would have the version number displayed for both as 9.0.8112.16421. On my other computer with an old installation that updated without problems, this is indeed the version number being displayed. Based on this observation and taking a cue from Spectrum7glr's post about installations prior to April 10 working perfectly, I tried to locate an installer that would have binaries before April 10. Luckily, I was able to find one from Microsoft's Download Center. Here's a link to the version for Windows 7 and Windows Server 2008 R2, 64-bit: http://www.microsoft.com/download/en/details.aspx?id=23332 Instructions: Uninstall IE9, if you already have it installed, and restart the computer.Download the installer.Disconnect from the internet. This is important because the installer attempts to download the latest, bad binaries from Windows Update.Let the install finish, and restart.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. Let me know if this works for you. I need to step out now, but will return later to perform further confirmation. Thanks and regards! Good luck to us. The above steps solved this problem according to another similar thread(http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/2c252dbe-c833-424d-9b75-4948bb8fb816). It turns out to be caused by the bad IE9 installer. Using an earlier known good installer worked.

Really? It's September and I've been waiting for this issue to be resolved. I have an update with the exact problem mentioned here and have been patiently waiting for this to be resolved without 'hacking' up my box in wasted time and effort to attempt to fix an issue that frankly should not exist. Especially after this long time and many, many update cycles. This isn't a priority? When can we expect this issue to be resolved the PROPER way by the manufacturer?Dodge

I found this article and it helped me resolve the same error code with other failing Windows Updates. It seems to be an issue related to .NET Framework 4. http://techbytesxpress.com/2012/10/10/a-new-official-tool-for-fixing-windows-net-4-framework-problems/
