Crackrjack's solution helped me as well and I appreciate very much this advice. I had this error some months before and I solved it with renaming the "SoftwareDistribution" folder to "SoftwareDistribution 1" (any other name works as well) under the Windows folder. You must be in Safe Mode in order to perform this operation. The Windows update created a new folder "SoftwareDistribution". But it didn't work this time. So this is greatly appreciated! Many thanks, Crackrjack31!

It keeps telling me it's failed to install.

Re: Problem With Download From Vista Error Code 646

dogus12: I had the same problem. I got this advice from crackrjack31, and it solved the problem. Click on Start.
Click Control Panel. Click User Accounts. Click User Accounts again. Click "Turn user accounts on or off". Click the box to turn off user account. Now run the update from Vista. It should work. Now go back and turn on User Account Control, using the path you used to turn if off. Good luck.

idea Re: Problem With Download From Vista Error Code 646

I found the best way to get the Update to finish, after going thru all the steps advised, except the managing the user control (I had no idea what that meant)...I went to Microsoft.com and searched for the codes that wouldn't download and manually did it that way. Restarted my computer and then clicked back on the Updates and it finished without anymore problems.

I think I should have just done that from the start. Going thru and turning off my firewall protection didn't help anyways, since I not only have Windows firewall protection but McAfee as well...which I couldn't turn off. So that didn't seem to help when I did that step.

Hope that this helps a little bit. Thank you to everyone before me for your advice...I don't think calling tech support would be a good idea, as you may end up having to pay for it.

Good luck to all!

Take care,
God Bless,
Julie D

Re: Problem With Download From Vista Error Code 646

Mom2Twins: Glad you solved it. I had it happen again yesterday and fixed it as before (learned from this thread). As follows:
click on:
Start.
Control Panel.
User Accounts
User Accounts (in the new window)
Turn User Account Control (UAC) on or off.
check the box to turn off UAC.
click "OK".
restart computer.
run Microsoft updates.
reverse procedure to turn UAC back on.

Re: Problem With Download From Vista Error Code 646

Thanks for the suggestion. I printed your response for next update. I'll try to remember to let you and others know if it does the trick.

But now I have issues with sleep mode. Won't stay in sleep for longer than 5 min's or so. Any ideas? I tried power settings--nada.

Re: Problem With Download From Vista Error Code 646

You have to make certain there actually is a sleep mode issue. You try it to put it in a sleep mode for a few times. If you are still having problem you are able to securely say you have a sleep mode issue. You have to see if your system's essential input/output system (BIOS) has sleep mode turned off. The Sleep mode and additional power-saving states are frequently turned off in a system's BIOS by evasion. Then you restart your system then the systems BIOS will come into view when the system boots up. After proceeds the BIOS setup arrangement. If then also not solve then you can contact the manufacturer so that they can solve your problem.

I don't know who originally told me how to remedy error code 646 (I did do individual updates from MS website, but it took too long). Then someone said turn off User Account Control. Whoever you are, just a word to let you know IT WORKS!!!!

Last couple of updates I shut it off(of course it asks to restart) but if there are 3-4 security updates, doing them one-by-one can be tedious. UAC in off mode is a snap. Just wanted to let you know--in case you wondered--your suggestion was successfully utilized. Thanks.

This worked for me! Would never had known about disabling UAC. Had tried stopping all firewalls with no luck.

Thank you for your post.

Re: Problem With Download From Vista Error Code 646

After a lot of frustration with 14 critical updates not working, I found the solution that worked for my computer:

1. Click on the Start Menu
2. Click on the picture above your name (the icon picture)
3. Go to the bottom setting: "Turn User Account Control on or off" and click
on it.
4. Uncheck the box and turn the user account controls off
5. Now go to Windows Update and all updates should install properly
6. Restart the computer and go back and follow the same steps once all
updates have installed and recheck the User Account Controls turning
user account controls back on.

I hope this helps. It worked for my Vista Dell system.
