I installed Defender and upon trying to get updated definitions received
error message 0x8007064c, saying that the installation source for this
product is not available. I tried the troubleshooting tips in a KB article
(http://support.microsoft.com/?kbid=915105) without success. Any suggestions?

Many thanks.
 
I appreciate all the replies. The solutions proposed by Engel did not work.
At multiple steps in the process, I received error messages saying that the
"installation source for this product is not available." Bill's reference to
918355 resulted in some progress. Using Windows Update, I was able to
install the most recent definitions file. Time will tell whether that file
will update automatically in the future or whether I will need to continue to
update it manually.

Thanks for your help.
 
That sounds good--as long as you are not on a managed corporate network, and
AutoUpdate is working, you should be OK.

You can do some testing by going to Help, about, and hitting the check for
updates button (within Windows Defender)--even if no update is available,
you should see a pair of balloon messages--one at the start of the check,
and another at the end stating that no updates were found.
 
Bill,

Thanks for identifying the location of the "update" button. You would think
it would be in a more prominent place.

When I click on the update button, the button goes gray and nothing happens.
So it appears that autoupdate is not working. Hopefully this will be fixed
in future versions, but for now it is a pain!

Thanks.

Mitch
 
I'm having this same problem and also have checked all the support
suggestions with no success.
 
Mitch--when you hit that button, it initiates an autoupdate--very much like
the autoupdates for other Windows patches.

Here's what should happen--you should see a balloon notification that the
Defender is searching for available updates. Some time later--minutes,
perhaps, you should see a second balloon stating either that Defender is now
up to date, or that no updates were found. Sometimes there is a balloon
with an error message.

If balloon notifications are disabled, you won't see any of this.

See #11 on this page:
http://www.kellys-korner-xp.com/xp_tweaks.htm

If you are on a corporate network (or using a machine that has been
configured for such a network) AutoUpdate may be set to connect to a
corporate server which may or may not have Windows Defender updates
available---analysis of the log file at %windir%\windowsupdate.log can
usually sort this out.
