Windows 7: Update Error 80070643

Windows Update Error Code 80070643

I am trying to update 4 identical PC's. They are Win 7 x64 Home Premium.

I am getting the following error on ALL the pc's -- they haven't been updated since February, 2010. Code 80070643. The second error in the pic is new, but the 0643 error occurs on them all.

Looking up the error, i found an MS support article saying its related to .net framework. I tried the few solutions on there and it didn't fix it.

I tried the Windows Update reset solutions on this forum as well as the MS Fix it tool. Neither fixed the issue.

Any further advice?

Remove completely 3p antivirus and firewall and try again

see also:You receive error message 0019-80070643 when you install Windows Live OneCare

If nothing help check in update history with which one updates you have problem.In mostly cases this error relate to issue with 3p security software and you have dispose them.

What is 3p antivirus? The only security software installed is Microsoft Security Essentials.

Other programs installed:

Returnil (deactivated for windows update) - antivirus part not enabled
OpenOffice
Firefox
Adobe Acrobat 10.1

That's it -- really. These are basic quick use computers in the business center of our condo building.

I strong recommend unistall completely both MSE and Returnil -if any security soft cause problem disabling it may not be enough to solve problem -even if you disable program it is still able to run some own processes.I know it is strange but it is.

Besides Returnil already include antivirus and MSE too -it is not good idea.You have practicaly installed two antiviruses.Even if you will solve your problem,leave only Returnil,MSE uninstall pernamently

Finally got this fixed, in case others search for this. I did not have to uninstall MSE or Returnil. Not sure which of the following steps actually takes care of the issue, but I did all of them on each PC and it allows WIndows Update to work:

1) Turn Windows Features On/Off --> Uncheck .Net Framework 3.5
2) Run Windows Update Reset Tool (Fix it) [Check "Aggressive Mode"] Article
3) Run .Net Cleanup Tool Article
4) In an elevated command prompt, execute (Article):
1. Bring up an elevated (Administrator) command prompt
2. Execute the following commands sequentially:
a. fsutil resource setautoreset true c:\
b. cd %windir%\system32\config\txr
c. attrib -r -s -h *
d. del *

3.Type: Cd c:\windows\System32\SMI\Store\Machine
Type: Attrib –a –h –s *.TM*
Type: Del *.TM*

*** You may get access denied errors -- its ok for now ***

5) Restart in Safe Mode with Command Prompt. Redo the steps above in BOLD. Some files still will not delete. That's fine.
6) Restart in Normal Mode - run windows update with success.

Hi Flavius,
Apologies for resurrecting an older thread, but I wanted to make sure you were aware of the following:

Uninstalling Returnil Virtual System 2010 or the new Returnil System Safe 2011 is not required as we have designed the Virus Guard component to be compatible with most 1st and 2nd tier Antivirus/antispyware solutions to support existing customer deployments where an AV may already exist on the client. As a general rule of thumb when installing MS/Windows updates however, turning off the Real-time virus protection feature in RVS/RSS temporarily (until the update is complete) may be useful.

It is the System Level virtualization and Anti-Execute features that are more important in update situations. The AE requires the virtualization (System Safe in RVS 2010, Virtual Mode in RSS 2011) to be active so simply turning off the virtualization (as noted by dokster) should be sufficient.

If anyone encounters an issue with RVS/RSS please let us know at our forums or via support e-mail to support (dash) tech (at) returnil (dot) com.

Thanks
Mike

Just now I registered in this forum to say you a big thank you, dockster.

With your above posting #5 you solved my difficult problem with the installation and also uninstallation of Windows updates. Both of them failed since more than a month now, always with the same errorcodes as in your picture in the first posting: in most of the cases code 80070643 and in connection with some of the latest updates also 80071A91.

For all this time I was looking desperately for a solution of the problem. But all methods failed - until I found last night your posting by searching with Google.

You describe 4 different methods and you write:

Well, from my experience I can say that methodes 1 - 3 did not work (on my computer). I had alreday tried them in vain before finding your posting.

But the solution of all troubles came with this:

I tried it - and it worked.

I had already lost the hope to find a solution, but your posting was the rescue.

Thanks again, dockster.

Thanks Dockster. You are a great. This error drove me mad and I searched high and low for a solution without much help until I saw your post. Got few errors following the instructions but it worked.
Once again, thanks a lot.

Thanks Dockster for putting this solution here.

Just like Peter123, I have registered simply to say thank you because of your post #5.

After trying all the MS fixes for .net Framework in vain, I executed steps 1 to 5 and it worked for me.

Windows Update is now working normally again.

Thanks again.

One of todays updates will probably not install.
Silverlight Security update.> KB2668562 - Microsoft Silverlight Failed to update. - Microsoft Answers

Quote:
Thanks to responses on this listserver, we've looked into the Silverlight update, have identified a metadata (logic) error and will be releasing a revision to correct this very soon.

Consider holding off on this update until a revision is published and visible in your WSUS/SCCM consoles - or simply allow auto-approval to permit the revision to replace the original version. We have similarly 'down throttled' unmanaged (consumer) machines until the revision is released (throttled at 0% = no consumer machines will get this installed automatically - but users who open WUApp and choose it, will still be able to run it - even though it will fail).
