On a Vista Home Premium machine, while attempting to download and install Security Update For Microsoft XML Core Services 4.0 Service Pack 2 (KB936181)I receive afailure each time with error code 643 and 8000FFFF. I welcome any feedback.

i got the same problem but i get error code 641

Me too, I've got Vista Home Premium and this also comes up with error 641. Cant find any answers anywhere.

I have also had a problem with this update. The update indicates that it installed successfully but it keeps prompting me to install it, over and over again.

Likewise unable to make that annoying yellow shield from Auromatic Update go away and recognize I have successfully installed this update seven times now... Finally just chose to ignore the update & install, but this is only a band-aid. Any recommendation, MS, on how to make your system recognize a successful installation and stop pestering me with an 'urgent update' ? Fed up with this nonsense... Looking for a solution

Same 641 error

I'm upto 23 of this is update with it coming back with each reboot.

Yep, Same as, But i'm on Home premium and have 15 installs of this update. I don't even have to turn the computer off for it to want to re-install!

I have the same problem. The update alert keeps popping up and I have "installed" the update 8 times. I even downloaded the update and tried that way to no avail.

Well, I think I found a solution, for XP at least. I don't know if this will work for everyone experiencing this problem, but here goes. I downloaded the update program "msxml4-KB936181-enu.exe" from the Microsoft site, not Windows Update. http://www.microsoft.com/downloads/details.aspx?familyid=021E12F5-CB46-43DF-A2B8-185639BA2807&displaylang=en I ran the program and told it to remove all. I rebooted and then ran the program again to install it. I then ran the Windows Update file for "Security Update for Microsoft XML Core Services 4.0 Service Pack 2". After reboot, the icon is gone and it no longer pops up. Yea!!!!! Good Luck all, TDeGrenier

thank you for your help, I had downloaded this update 7 times and now it is corrected...

HI .I tried to download XML CS4SP and uninstalled it from my computer. then I reinstalled it after reboot. but I found that the update still come up. so I uninstalled it again and installed the update from vista windows update.

I have the same problem, no error code but keep coming back for the same update, have you solve the problem yet? If so, mind to share that with me.

OK I have a fix for the Vista issue of this problem.Go to Start > Settings > Control Panel and select Programs and Features. Then Uninstall all entrys related to Microsoft XML core services (These will be clearly marked)Then close everything down back to the desktop and do a search for updates and you should get the normal 1 XML Core Services 4.0 update. Unstall this and it should fix the problem.

have also had a problem with this update. The update indicates that it installed successfully but it keeps prompting me to install it, over and over again.

TRYING STEPS BELOW @ 3:31P OCTOBER 24 WEDNESDAY "OK I have a fix for the Vista issue of this problem.Go to Start > Settings > Control Panel and select Programs and Features.

This same installaion has occured onto my PC more than 70 times. I need to know why it keeps prompting for it.

thanks. it works. It hasn't bugged me since I have all xml uninstalled and reinstalled. Now I have another problem... Cable plugged in but not charging. It happened once last month but don't recall how I get it charging again. It happens againout of the blue. I plugged it in for awhile and expected itto be fully charged, instead I got emply battery icon with a message of plugged in but not charging. Itcannot be loose cable connection because without plugged in, notebook would be dead and my battery is only10 months old. Can someone help? Thanks.

I downloaded the update program "msxml4-KB936181-enu.exe" from the Microsoft site, not Windows Update. http://www.microsoft.com/downloads/details.aspx?familyid=021E12F5-CB46-43DF-A2B8-185639BA2807&displaylang=en (from previous posting) I used this for the same issue on Server 2003 and it solved the problem. I ran the removal tool, ran the installation tool, then ran the update one last time (did not reboot at all during this time). It has not come back since. Thanks for sharing!

I am running XP. I used TDeGrenier's solution, but I first had to uninstall the Windows Installer 3.1, reboot, reinstall Windows Installer 3.1, and then reboot again. When I uninstalled Windows Installer 3.1, it gave me a warning about application dependencies, but I ignored it without any problems. I figured it didn't matter since I was going to reinstall it right away anyways. And it seemed to work without a hitch, but I could be wrong. I don't recommend this method, and I would try the other solutions first, but if you're determined to try it: Google: Windows Installer -- for the download, or go here: http://www.microsoft.com/downloads/details.aspx?familyid=889482FC-5F56-4A38-B838-DE776FD4138C&displaylang=en You will need this to reinstall, so grab it first. You can uninstall it from Control Panel -> Add/Remove Programs, btw. Use at your own risk. And good luck.

FANTASTIC! Worked like a dream...

Worked on our win2k3 server. Thanks.

I have same exact problem. Is this installing each time and taken up space on hd? i TRIED INSTALLING FIX kb927978 and it tells me administr has set policies to prevent install? This is just a personal laptop? Are there ant answers to this problem?

This worked for me tooin Windows XP. Thanks!!!

I too have had the same problem. Installed it numerous times, my history shows its installed. Is anyone at Microsoft awake? The problem should have come to their attention via their own systems checks, been rectified and an answer sent out to one and all using their products. My bigger concern is whether or not this is holding back other updates that should be appearing or downloaded via the Automatic Update function. TSawyer56

I just read the solutions posted for the XP user. My only problem is I haven't a clue what it all means. I tried following some forum solutions a couple of years ago when I first got a computer and totally screwed it up, costing me a few hundred dollars to get the thing back to normal. Still being a novice, I am reluctant to start navigating through things I don't understand. Seems strange to me that users have to come up with solutions to a manufacturers products. Ahh, Customer Service.....another American myth along with Big Foot and Extraterrestrials!! Have to admit I did get adventurous by typing in the xml info in the address line as a last ditch frustrated effort. TSawyer56

For the longest time I've been dealing with that darn shield popping up. When I try to shut down, it tries to install that darn update. If I had known it was something so simple as this.... *smacks forehead* Thanks for the advise!!!

Before I uninstall these, I want to make sure that I'm not uninstalling something extra (I am running Vista Ultimate 32). So, I have 3 programs listed: MSXML 4.0 SP2 Parser & SDK, MSXML 4.0 SP2 (KB925672) and MSXML 4.0 SP2 (KB927978). Is that it? Are there supposed to be anymore entrys? Will they all reappear after I doa search for updates? Thanks for the help!

I AGREE WITH YOU,UNINSTALLED THEN REINSTALLED WITH YOUR HYPER-LINK..THANKS FOR THE HELP,,,LOL,,,WAS GETTING VERY UPSET WITH IT !!!!!!!!

MAY NEED TO CHECK FOR A NEW DRIVER UPDATE,,OR LIKE ME IS A LOOSE CONNECTION ON THE PLUG ITS SELF.

It worked for me without rebooting at all. Thanks, it was driving me nuts! TDeGrenier wrote: Well, I think I found a solution, for XP at least.

Yes after many weeks/months of this, I did a search and ended up here, downloaded the fix then tried running the windows update symbol, it installed again. then a few seconds later there was internet activity... and the windows update symbol once again, opened it, same xml update. I ran the fix yet again, its still there. I clicked the symbol but this time unchecked the box and closed it, then went to the Microsoft website and did a search of that xml update, and manually did the update from there, it askedto agree to the license, yes, ran it, this time it says it must reboot to finish, so I rebooted... no symbol. waited a while, internet activity, no symbol, thought great its all fixed. rebooted again, still no symbol. powered off yesterday aft. and today? the symbol is back, same xml update... I clicked and let it install. watched and again the symbol is there right now. My explanation for this is that I dont have an explanation. but am willing to try this in a specific sequence

When I open control panel and select Programs and features, I do not see Microsoft XML core services but I get the same problem everyone else mentions. I select to down load update and it says it was successful, but the next day it appears again.

Thanks for the information, for the first time in tw0three weeks, I do not get the update icon on my PC, This fix does work for Windows XP pro

I cannot find any xml installed updates but am now working on uninstallling recent updates numbered higher than 936181 The security update for microsoft xml core services 4.0 service pack 2 kb936181 has installed seven times on June 17 and 18, 2008 and is not really installed in the control panel but shows on the update window that keeps popping up. Sarah

I also tried to download off of this link, and it only goes so far then a box pops up and tells me that I have to have the CD to install ..??...think you might can help me on this problem...?? thanks...

Hello: Can you explain this more clearly since I am totally pc ignorant. I have the yellow shield on the taskbar for a month and it keeps trying to download the service pack and it lists in the download history it has downloaded it several times in the past month.

ok, so i just tried that and it wouldn't work. because there was some installation already in progress and i coulnd't remove or stop it. i got in touch with hp and they gave me a few steps that i will forward on to you all. please remember to read carefully and make sure that this specifically matches your situation. And remember to make sure that you have your system to automatically create a restore point so if you need to you can go back. also, i had a windows search 4.0 get installed the same time, but it wasn't listed as a x64 vista home premium update. so i removed that too and did all thesteps. after doing all this, i got the windows search 4.0 for windows vista x64 based systems, which might have also been an issue. TRY TURNING OFF YOUR ANTIVIRUS SOFTWARE WHEN RUNNING YOUR INSTALLS. KEEP IT ON WHEN DOWNLOADING THE CONTENT FROM THE URL's BUT ONCE DOWNLOADED AND REBOOTED WITH THE SETTINGS AND STARTUP TASKS OFF. THEN TURN OFF YOUR ANTIVIRUS AND BEGIN INSTALLING. IF UNCOMFORTABLE, RUN A SCAN ON THE FILES BEFOREHAND. you might want to try this first. if have the install problem saying something is already in progress or the regular steps don't work for you. These are the steps to stop any un wanted process or program from running during start up.1. Click Start > Type Run in the search box and press enter. 2. Type MSCONFIG 3. Click OK 4. Click STARTUP tab 5. Uncheck all the programs except RECGUARD, KBD, PCHBUTTON, NISSERV.EXE, NISUM.EXE, Ccapp, Cfgwiz and CCRegVfy if listed. 6. Click OK 7. Restart the system If some of the programs mentioned above is missing, it is normal. Please continue with the instructions. After Restart in the pop up window put a checkmark on "Don't show this message or launch system configuration when windows starts." option and hit Ok. Here is what the main part of the install is. Step 1: Download Microsoft Windows Installer CleanUp utility 1. Please visit the following link to download the tool: http://download.microsoft.com/download/E/9/D/E9D80355-7AB4-45B8-80E8-983A48D5E1BD/msicuu2.exe Please copy and paste the entire link in a new Internet Explorer window. NOTE: The URL above will take you to a non HP Web site. HP does not control and is not responsible for information outside of the HP Web site. 2. Save the file to the computer. 3. Double click the msicuu2.exe to install this tool on the computer. After doing that, please take the following steps to remove previous installation of Microsoft XML Core Services.Stefan D: Step 2: Remove MSXML software 1. Click "Start" -> "(All) Programs" -> "Windows Installer Clean Up". 2. See if you can find MSXML 4.0 Service Pack 2 or its updates. If so, remove them. 3. Restart the computer. After that, please try to reinstall MSXML 4.0 Service Pack 2 and KB936181.Step 3: Reinstall MSXML 4.0 Service Pack 2 IF THAT DIDN'T WORK.... THIS WILL. 1. Please download the following files and save them to the Desktop. MSXML 4.0 Service Pack 2 http://download.microsoft.com/download/9/6/5/9657c01e-107f-409c-baac-7d249561629c/msxml.msi NOTE: The URL above will take you to a non HP Web site. HP does not control and is not responsible for information outside of the HP Web site. Please copy and paste the entire link in a new Internet Explorer window. MSXML 4.0 SP2 Security Update (KB936181)Stefan D: http://download.microsoft.com/download/9/4/2/9422e6b6-08ee-49cb-9f05-6c6ee755389e/msxml4-KB936181-enu.exe NOTE: The URL above will take you to a non HP Web site. HP does not control and is not responsible for information outside of the HP Web site. Please copy and paste the entire link in a new Internet Explorer window. 2. After the files are downloaded, please double-click the files to install them in order. BE AWARE OF THE NAME YOU SAVE THEM AS. AND MAKE SURE YOU DO SAVE TO DESKTOP SO YOU CAN FIND IT EASILY. MAKE NOTE OF THEM AS YOU SAVE, SO YOU CAN CHECK WHICH ONE WAS SAVED FIRST. also, i had noticed that i got an error saying the log was not found for the second install. just try to re-download it. otherwise just restart your computer with all the startup tasks back on. After that, please access the Windows update site to check if this issue has been resolved SO FAR SO GOOD. FOR ME THAT IS. GOOD LUCK! oh yeah, i also cleared my history, cache, cookies and temporary internet files before doing this all. just to make sure there wasn't anything keeping my computer from thinking this was all fresh.

This guy is a genius sort of i thought it did work just forgot to mention that there are two types of Knowledge Base Files... one being called MSXML 4.0 SP2 (KB936181) and the other being called MSXML 4.0 SP2 (KB941833) so when you find that theres another update with the same name, dont be shocked its just another update... doesnt mean that its not worked, you just need to install both parts tofix this problem and then you're sorted! Cheers Again!! ^-^

Thanks for the heads up TDeGrenier. I am running XP with SP3 and the fix worked for me. Itried the install 8 times and couldn't get rid of the update icon until I tried your solution. Cheers, Sarairmech

My computer keeps advising me of the need to INSTALL this update. When I install it, I don't get an error message. It SAYS it is installed, but minutes later, the reminder comes up again. I've installed the darned thing about 40 times, and it STILL reminds me everyday.

Same here........I've lost count of how many times I've installed this darned thing, and it STILL reminds me EVERY DAY.........several TIMES a day. I'm really getting fed up with it, and can't find how to report the thing to Microsoft without paying $59 for their support program. This is THEIR problem, you would think they would solve it for free.

T you are a GENIUS !!! After two or three months of dealing with this pesky lil twerp, YOUR solution fixed it !! THANKS SO MUCH.

Excellent post TDeGrenier!! Thanks for including the link. After NUMEROUS tries (and failures), your advise worked like a charm. Thanks for allowing me to see the forest- I guess all the trees were in my way! Good job!! Rob62

Thank you so much this worked and the annoying yellow update shield is gone, did what you said above. Awesome, Thanx!!

Hi, I have the same problem, but my updates are not "clearly marked", so I have no idea which to uninstall. Any ideas? Thanks.

Hi, i AM EVER GLAD THAT I AM NOT THE ONLY ONE EXPERIENCING THIS PROBLEM. AFTER USING THE AUTOMATIC INSTALL AND INSTALLING IT ABOUT 10 TIMES SUCCESSFULLY, I DECIDED TO MANUALLY INSTALL IT AND I GET AN ERROR MESSAGE: " ERROR OPENING INSTALLATION LOG FILE. VERIFY THAT THE SPECIFIED LOG FILE LOCATION EXISTS AND IS WRITABLE" Has anyone else had this error.

Hey yea iv had a problem with the same update apart from i dont get a error code or anything it says it is sucessfull but then it persists on making me download it over and over. I cant think of anything to help fix this if anyone has any answers please let me know.

Hi, I had a friend that complained about this for his Vista OS. I went to the download site and found the following... Supported Operating Systems: Windows 2000; Windows 98; Windows ME; Windows NT; Windows Server 2003; Windows XP Don't know if this make a difference or helps any one, but It says its not suppored for Vista. Check it out yourself if you'd like.

I downloaded the file from Microsoft.com also. Tried doing the 'repair' option first but that didn't help. Then after reading these forum posts, I tried the first option of removing it and reinstalling it with the same file I downloaded. I was still receiving the update error afterwards. So as this user posted below, I removed it with the downloaded file from Microsoft and reinstalled the update from the Windows Update tool and now the problem is solved! Been doing it for months and I should have looked for information on how to fix it sooner.
