Defender does not update and brings up the above code - any suggestions. It
also comes up with a 80070714 error.
How do you uninstall Defender?
 
Hello Craig,

0x80070643 -2147023293 ERROR_INSTALL_FAILURE

Are you on a large, managed network, where access to AutoUpdate is
restricted?

Is there a WSUS server on the network?

If the answer is yes, maybe this can help:

Are you running Windows Live OneCare?


Try to fix your problem with:

Download Ccleaner and Dial-a-Fix


CCleaner
Ccleaner - http://www.ccleaner.com
Note, uncheck Yahoos toolbar during install.

Do the scans with all the check marks on.
Open Ccleaner and press "Windows" "Aplications" and "Run Cleaner" from the
menu choose 'Issues' and then press scan for issues, Repair any fºund.


Better if is run in safe mode.

Run the above clenaer in safe mode. Ccleaner with all 3
settings(windows,apps &
issues) and clear anything found, reboot and see if Windows Defender update.

Registry

CCleaner even has a built-in Registry Cleaner. It's not the best (not
CCleaner's main function), but it will find invaild registry entries that
most Registry Cleaners will not. Unlike the Disk Cleaners with a Registry
Cleaner, CCleaner does really fast scanning for Registry Issues. The reason
is CCleaner doesn't want to effect Windows performance or effect any
applications. It's better to be safe than sorry!

The first time you run CCleaner's Issues scanner you'll have to keep running
it back-to-back until it finds nothing. One scenario is a registry key may
only be a reference pointing to a completely different location in the
registry and when it's removed then that reference link is also noticed as
being invalid on a subsequent scan. It's generally a good idea to keep
running the Issues scan until nothing is listed.



There is also a third-party fix which has had good results for a number of
folks here:
Dial-a- Fix
http://wiki.djlizard.net/Dial-a-fix
Scroll down about 2/3 of the way to Download Dial-a-fix

Run this program with all the functions activated in safe mode.

Dial-a-fix is essentially a scripted run through of the standard Microsoft
fixes.


You can unistall WD going to the Control Panel – Ad-Remove programs.

I had the same problem, i found it to be Spyware Doctor, i disabled OnGuard
ran the update again and it worked fine. If you have Spyware Doctor installed
then dissable OnGuard first.
 
Hi Craig,

I use the belt-and-suspenders mode. Make a Restore Point.
