RE: Code 646 in updates

Glenn, did you find a solution. I keep getting the same message. Also, I get
code 643. I am very computer stupid, so I don't understand a lot of the
language. And it keeps wanting me to update, over and over. I click to
update, it says it is doing it, but then my computer restarts, and asks me to
update again. I have been doing this for HOURS. Can you help. I really need
step, by step instructions.

Have you tried inserting your Office 2007 CD into the appropriate drive bay
before attempting to install the updates again?

You can add me to teh list of people with that problem Running Vista Home Premium and Office 2007.

Anyone else i too am getting code Ox643 when trying to install
..NET FRAMEWORK 1.1 SERVICE PACK1 SECURITY UPDATE,it will not install,anyone
know how to fic this?

It has nothing to do with not havingIE8 installed, because I do and am having
the same problems.

I've been getting the 646 error on all most all of my updates for the past
week or so. I can click on "review your update history" and then click on
each one and manually download and install them (which works) but with as
many updates as Microsoft puts out, this is not a viable solution.

I to am getting this error , please help. Are these updates that important.
Ive tried several things and Im still getting the error message.

I have all together or one at a time. My problem has only been since
the 16th Oct so not been happening for long. (i am also using Windows Vista).

My PC won't install these latest updates and I too get the code 646 error
msg. Could it have anything to do with not having the new IE8 installed?
Anyway, now I do not know how to shut the update icon down (bottom right
corner) it is constantly telling me I have new updates to install. DUH! I
know that, but they will not install. I hope someone finds a solution to this

Why do you think Bill Gates is the richest man in the world? You
try calling Microsoft and they turn on the good ole taxi meter,they do
nothing for free,none of us do or would,but the issue here is that MS
controls the computer world,they devised the software,they should notify and
present fixes if their installation updates don't work,which is the case
here.Maybe some conscientiousness MS manager will take pity on us fools and
post a easy,step by step fix.

If you click on optional downloads and download them the rest will install
also, KB973709 KB972581 KB974234 AND KB973636

You need to install them manually. Go to Microsoft.com search for the KB
number. Download and install. I was getting the same errors and this will
correct4 of the 5. However I do not have MS Visio on my machine and for some
reason it still thinks it need to install the patch. Which will fail since a
pre-req is MS Visio.

I can't install the three updates either, have tried everything suggested, no
joy just keep getting unknown error 646, help please, they appear to be the
same updates, also I have KB97363 which wont update

hey Duffer,i upgraded awhile ago for IE #8, i dont think it has anything to
do with IE#8,this started happening to me as of yesterday and i haven't
downloaded IE.My problem is i tried alot of fixes suggested including MS's
site and none seem to be working for me.I also cannot get rid of the yellow
shield showing updates.I am wondering whether it is necessary to TURN OFF WIN
updates first and then try the fixes and then rebooting.It seesm to me that i
tried that one too and still no success.If anyone had any idea of what the
heck the fix is in plain simple steps,we would appreciate a stepby step fix:)
bigalster on verge of nervous breakdown

I thank it is something with the upgrade of Explorer 8, Reasons:Iam
running Secunia PSI and it said that I had a 90 something secure and upgrade
rate one of the highest for the whole state of KY... But that was before I
tried to download an option of Internet Explorer 8 and then I now have the
following unsecure programs 1. Ask toolbar 4x...2. Microsoft Internet
Explorer 8....3. Real Player 11...My computer come with Vista Home
Premium,and I am now running the Windows 7 Beta test... Which after
researching thought Micrsoft Internet 8 had even more componets as well as
some more new features is the only reason I tried it "What a big mistake that

I too have said in several posts, if anyone
has just plain language (not computer lingo, there are still a few of us out
here who have no idean what you mean) step by step instruction that work,
please tell us. I am getting to the point where I just want to unplug the
computer and protect it that way. Is Microsoft even reading these posts? My
gosh, you would think they could see that there are a ton of problems w/these
latest update installations. They should fix then send a mass email to those
of us who have windows that the problem is fixed now try it. Oh and does
anyone know if Microsoft even has a ph.#. I know that sounds like a silly
question, but I cannot find one. I am getting no answer or help online. Sorry
this is so long.

I have gone to the point that I have
totally uninstalled and reinstalled office 2007 home and student on
windows vista basic system. I have tried installing them singly with
no results. I am able to update everything except office 2007. I
would sincerely appreciate help before this poor little laptop goes
flying through the air. There has to be an easy solution here.

Has anyone come up with a solution? I'm having the same problems with KB973709, KB972581 and KB974234

i have found a way to download these updates, go to the download center,
individually type in the updates code starting with KB and download them one
at a time, it should fix the problem, it worked for me.

Re: Code 646 in updates

I have the same freaking thing!! I have gone to the point that I have
totally uninstalled and reinstalled office 2007 home and student on
windows vista basic system. I have tried installing them singly with
no results. I am able to update everything except office 2007. I
would sincerely appreciate help before this poor little laptop goes

Some please help

<cmd_output OS="XPsp3">
E:\>set /a c = 0x646
E:\>net helpmsg %c%

Feature ID not registered.

I think you're going to have to figure out what "Feature ID"
is being referenced here. Search any files that the update
creates or modifies as if they were diagnostic files, looking for
instances of 646 and 1606 and report their context.

BTW please figure out how to stop Google Groups from making
your replies come as if they were HTML (Quoted Printable).
Plain text is preferred in newsgroups.

So what you are saying is the solution given several times over...

Install the updates manually.

It's not a solution, but a work around. Most who are having trouble and do
this work-around will likely be back next month (second tuesday and after)
asking the same question about how to install some update because of a
failure to install. Until they fix their updates system, it will repeat
each month.

Also - the easiest way to download any update Microsoft releases and do this
manually is to plug the KB######'s into this web page:

In this case:

From which you should click on the link for IT Professionals:

Where you can get the proper update for your version of Office.

They will also want to check the original link given to ensure they meet the
"Prerequisites to install this security update" and they might even utilize
the section on "How to obtain help and support for this security update" to
their advantage.

I can not emphasize enough how bad I think this advice is.

Installing a *BETA* version of a software (unreleased and unsupported) to
fix a problem *some* people (not all by a long shot) are having with a
current and supported product... Horrible, horrid and unwise at best.

Plus you are assuming everyone will want/can afford to purchase Office 2010
(or has the knowledge/will to steal it) when it is actually released and the
knowledge/skills to remove the beta and install the full version.

I did all this and still failed. I turned off firewall and it went through 12
of 13 installed then failed again. Any other suggestions.

I did it the old fasion way, which was slow file by file via manual download
from MS . IT WOKED

Or was that Elmer Fudd for "Rocked"?

What operating system do you have?

For example:
Windows XP ______ Edition with Service Pack _ __-bit
Windows Vista ______ Edition with Service Pack _ __-bit
Windows 7 ______ Edition __-bit

I'am really new to this, all I can find is the questions on here. Where do
you find the answers.

I keep getting the same error code - I am wondering if it has to do with not
having "Office 07, ie Word, Excel, and PowerPro" installed. When I bought
my laptop I decided not to opt for Office 07 and instead I just use Works
which came loaded. It seems these 3 updates are connected to Office
products. Anyway - I just unselect the updates and only load the ones that
aren't connected to these 3. So, this is my uneducated solution and I would
really like to know what Microsoft is saying the reason is that these aren't
loading...please if anyone knows - pass it along. Thanks

Linda, I have noticed, that all of the updates that this relates to are for
Microsoft Office Home & Student 2007 is that true for you also, or did you
start off with a trial version of the software, and then purchase another
version from the store. These are related, I am sure, based on the history
that I am seeing. On a quick note, I see no solutions indicated from

UPDATED as I noticed that I had left some small & possibably important parts
of the instructions, I apologize for that!!!!


Go to start> Control Panel> Adminstrative Tools> Services> When you scroll
down to this (Office Source Engine), right click on it and make it AUTOMATIC>
then click the apply button then click the Start button. Then restart your
pc, then manually download the updates above it they are (as this is what I
had to do to get the updates installed on my Windows PC, I am running Windows
Vista Ultimate 32bit system) the ones that I could not get to install using
Windows automatic update. This is the process that I had to go through to
install these updates on both my wife's PC and my own PC.

1. Search for 646 MVP. (E.g. press Alt-7, type that and press Enter.)
2. Try the filters. Alt-i Enter, Threads with helpful posts Enter
3. Click on the [+] (or doubleclick on the the discussion title.)

Hint: use the Help button (at the top right.) (Alt-m, BackTab, Enter)

Doesn't work for me, and I know what the problem stems from..... somehow, somewhere, some registry entries were corrupted or deleted.

Amazingly, this problem doesn't occur on Windows XP or 7.... it only appears on Vista, and only appears when there are 'junk entries' in the registry on Vista. By junk entries I am talking about registry hives with........ random letters, symbols and numbers like "HOHLKDHLDKHDLDHDLH!" as an example

Didn't work for me... tried downloading the things and installing them manually.... still failed and also.... the manual installers crashed!

Microsoft needs to release a 'fix Microsoft Office' tool, that goes through the registry entries and either deletes them all or fixes them all.

I've done the 'hard manual uninstall' thing recently on my parents computer that Microsoft recommends, and it's a pain. Even installing them using the things in the 'Installer' directory in the Windows directory, it still fought me every step of the way.

None, to be honest. Personally, I just went the 'tough route' and downloaded the Microsoft 2010 trial and installed it on all my machines that needed this or I wanted this on..... and it's working well thus far.

Little problem....... it doesn't always work. I've tried 'installing the updates manually'.... it just doesn't work if the Microsoft Office Installation registry keys have gotten damaged..... the thing will just 'crash out' without even giving an error message or any other information.

Microsoft has rewritten their installation thing for Office 2010 (also known as Office 14). Supposedly..... this issue is now GONE PERMANENTLY. I would advise anyone who is having problems to just go into their registry, delete EVERY mention of Office or something connected with the office suite, and download the Beta version of Office 2010 Professional off the Microsoft website.

So far, I have not seen any problems with Office 2010 AND those 'strange registry entries' that I alluded to in another posting on another subject? GONE!

Not one has appeared since totally uninstalling Office 2007 Home and Student, and updating to the 2010 Professional Beta.

(11/21/09) - I have Vista (64bit version), and I was getting this error for
three weeks myself. Thanks to one the suggestions below, I got it to work.
The suggestion that worked for me was to "manually" install each update
"individually". I could not use the windows automatic update feature. Here's
what I did (BTW, I did not have to turn off my firewall to do this):

1) Went to Bing.Com
2) Typed in the exact name of the update as it was displayed on the Windows
Update Screen (e.g. Security Update for Microsoft Office Excel (KB######)
3) Bing found the exact match to what I typed in on the Microsoft website
4) I clicked on the link
5) Selected "Download"
6) And Viola, it worked :-)
7) I repeated this step four more times, and now I've successfully installed
all five updates that I'd been trying to install for three weeks.
8) Thanks again to all of the tips people listed below, that was helpful and
the "manual" update tip worked for me.

Hope this works for other people as well.

RE: Code 646 in updates

My computer failed to auto load service pack II and never did let me know
untill microsoft says it will no longer upgrade any computers that don't have
II installed. I guess we will all have to but Mac's. Because microsoft will
not help us.

Don't let the door hit you on the way out to visit the Apple store. Take
lots of money, and don't plan on using much of the software you've gotten
used to.

Re: Code 646 in updates

Assuming you're referring to WinXP SP2, free unlimited installation and
compatibility support was available from late August 2006 thru May 2009.
Such support will cost you US$59 or higher per incident now. You snooze,
you lose.
