Help! I get a Widows Defender "failed to initiate" window at start

My windows defender keeps failing to initiate at startup. Instead, I
received a small popup window that said that defender failed to start and I
should either restart my PC, (which I did, and it continues to fail to
initiate), or go to the help and search to start a program manually. I tried
that too, but I get the same popup window about failure to initiate. What
went wrong? How do I get windows Defender to initiate upon startup like it
was before? I can't even find out which version I am using because it won't
open.
Thanks!!

I also have a PC which is experiencing this issue, I've checked the local
services and when trying to start the Windows Defender service manually I get
a message saying:
Error 0x80071b90: The system license has expired. Your logon request is
denied.

Anyone have any ideas please?

OS= Windows XP Pro

The beta has expired. Windows 2000 is no longer supported. If you're running
XP you can download the release version here:

I'm also experiencing the same problem with Windows Defender, the error is
0x800106ba, I've tried to find a solution on Microsoft's website but found
none. It was fine yesterday and start acting up today, personally I think the
program had a time bomb installed and it just went off. Remember Microsoft
Antispyware beta 1 had a similar ending to it!
 
Hi there I too have exactly the same problme I am runnign XP Home edition and
this probome only started when I opened up my computer this afternoon.

Had the same problem and it seems the licence agreement in the beta version
was set to expire on 12/31/2006 disabling windows defender starting at
start-up. Un-installed the beta version and downloaded the new version from
microsoft's website and every is working fine now.
 
Same error here.

Posts below say to remove (expired) beta and install updated WD.

But when I tried to download, I was asked to download and install the
Windows Validation program - which I DO NOT WANT TO DO.

ALL of my programs are honest programs so validation would NOT fail.

Because there are other issues with WV I don't want to install it.

Any work-around???

I have the same exact problem, Sinseh, and it began this morning, 31 Dec 06.

If you get any response/help, please post it so we can all "get the fix."

Thanks, Perry
 
For the record - the following is the complete message -
" WINDOWS DEFENDER - Application failed to initialize 0x800106ba A problem
caused Windows Defender Service to stop. To start the service, restart your
computer or search Help and Support on how to start the service manually."
If the Microsoft solution is to uninstall and re-install Live Care One -
I'll opt to simply uninstall and move on.
 
Wow!
Thank goodness I discovered this site.
I'm so useless with the computer. When the "Windows Defender..."message
popped up, and I turned off the computer and started it again etc. and the
message popped up again, I was convinced I'd done something terrible and
pressed the wrong key.
I feel so much better now I see it's a shared problem.
I have Windows XP. How do we sort things out?
Simple instructions please.
Thanks.

Fixed Problem - with help via Chat Session/Windows One Live Care - as follows:
Go to Add/Remove Programs and uninstall Windows Defender - next go to
www.windowsdefener.com and follow link to download new version (2007)
Windows Defender.
Whole process took about 5 minutes.
 
BillB, you're a Hero! Thanks for your efforts and your help to the rest of us!

Happy New Year!

The fix mentioned in here, going to windowsdefender.com and downloading new
version, after removing old version, works, Thank you.

At the same time, my screensaver stopped working and still does not work,
does anyone have any suggestions?

I tried this but during the download I got a message that "this installation
is not supported by this process type. Contact your product vendor". What am
I doing wrong. I have windows XP home version.
 
Sunil;
You have windows XP home, but in the standard 32 bit flavor, not the much
rarer 64 bit operating system version. So you need to re-download the
standard 32 bit version of Windows Defender from Microsoft which is named
"WindowsDefender.msi"
 
Dave

Thanks a million. That worked. I don't know why I clicked e64 version.
Thanks again.

Sunil
 
You're not alone there, I think that 64 bit download needs the further
clarification that it's not for the standard XP 32 bit installation in the
WD download pages as many people report making that same mistake. The
average computer user has no idea of what x64 even means, nor do they want
to dig through the fine print to find out:

From the main download page:
"To download the x64 version of Windows Defender, click here"

Then on the linked x64 page but buried in the verbiage and at the same font
size:
"Please be sure to use WindowsDefenderX64.msi for 64-bit platforms."
