When I run update in Window Defender the following message appears.
"The program can't check for definition updates
Error found: Code 0x80004002"
Can anybody help me with this?
 
Hello Tasha,

Suggest cleaning up the system (clearing out all the Temp/Tmp folders, and
included all offline content, clearing the browser TIF , Delete Cookies , do
a Disk CleanUp.

Click the Start button . In the Search box, type Disk Cleanup, and then, in
the list of results, click Disk Cleanup.


Empty user and system "temp" folders.

Go to Start > Run > copy and paste the below into the Open: line

%systemdrive%\temp


%systemdrive%\%windir%\temp


%systemdrive%\Documents and Settings\%username%\Local Settings\Temp


Reboot


Try going to

http://www.microsoft.com/security/portal/

Under "Latest Definition Updates", choose your operating system type, 32-bit
or 64-bit, and try the manual download.

Note here the instructions pertinent to Vista:

I hope this post is helpful, let us know how it works ºut.

Hi Engel
I cleaned the computer as per Your instructions, rebooted, but the same
error occours. Anyway, I downloaded manualy the latest definitions and I
think this would be a future daily task for me.
Thank You for Your help
 
Hi Tasha,

I don't agree with << this would be a future daily task for me >>

Nobody have to go that way.

Something is out of aligment in your PC

They are a few quick remedies to try to fix it.

1.- Can you go to Windows Update, select Express (Get high-priority
updates), and apply all offered updates
http://update.microsoft.com

Once that is finished, can you verify the update installs? There are many
pre-requisite files which are needed from windows update and signature update
with windows defender will fail until you have these f!les.


2.- Give a Dial-a-Fix a chance.

Reboot into Safe Mode (F-8)

Run this program with all the functions activated in safe mode. --it may
look as if the scan has frozen. DAF is actually doing lots of shoveling and
shuffling, so don't interrupt it.

Exit Safe Mode (Reboot)

Next Tuesday or Thursday, try the updates

I hope this post is helpful.

Let us know how it works ºut

PS
One more fix is to repair WD, but let see if the above steps do the trick.

1.Open the "System Properties" window

a.If your Start menu is configured for Classic Start menu, right-click the
My Computer icon on your desktop, and click Properties.
b.If your Start menu is the Windows default Start menu, click the Start
button, then right-click the My Computer icon in your Start menu, and click
Properties.

2.Click the Advanced tab.

3.Click Environment Variables.

4.In the "System variables" list at the bottom of the Environment Variables
window, look for a variable called "PROCESSOR_ARCHITECTURE". If your PC has
a 32-bit processor, this variable will have a value of "x86". If it has a
64-bit processor this variable will have a value of "x64".
 
Use 32-bit unless you know otherwise.

What matters is the version of Windows, not what the processor is capable
of--the vast majority of 64 bit processors are running 32-bit versions of
Windows.
 
Thanks - good to know the right answer!
