error message 0x80070002 and reinstalling Defender

G

Guest

When I click on defender I get an error message 0x80070002 and when I try to
reinstall the product is says I can't because defender comes with Vista
(which is the operating system I am using).

Any help?

Jeff;

I think you're saying that you managed to remove Windows Defender, even
though it's part of the Vista Operating System, and now you want it back by
trying a re-install. Is that correct, or are you just trying to repair an
existing, but possibly damaged installation?

Specifically are you getting the error "Application failed to initialize."
If so, this is not what you want to hear, but it is the official Ms KB on
the issue:

I have the same issue but never ever uninstalled Defender! This issue just
popped up. There is no way in hell I'm even gonna try to remember when the
issue started (June ish last year) as it took me this long to find the issue
on site. YOur application error. You fix it. As long as there are systems
possibly open to spyware infestations, Vista systems are a threat to
EVERYONE. Is the company up for that?

Carlos - nobody here, with the occasional exception, works for Microsoft.

This is a peer support group.

Let me clarify some background here: Is your Vista installation an upgrade
from Windows XP?

The option in the KB of reinstalling Vista is (or may be, at least)--much
like a repair install on XP. It takes a good deal of time, but in the end,
everything is just the way you expected it to be--no program reinstalls are
needed, for example.

If this was an upgrade installation, do you have Vista media to do a
reinstall from?

I'm not closing out other options--all that I've done so far is noted your
error message, and checked that KB article which Dave referenced to see
whether it had any revs--and it didn't.

Yes Bill I do have the Vista Upgrade installation disc (somewhere). I guess
I'll have to dig it up and try the suggested method, but I really hate repair
reinstalls (I guess that I remember ME and the early XP problems too well).
Perhaps I'll try it AFTER doing a backup and while watching The Doctor.
Do wish there was an easier way. :-(
And sorry if I was a bit snippy. It took 3 tries even to get to this part of
the site last night, kept getting kicked out to "update" my profile.

I wouldn't be too quick to do this either.

I've done it just once, myself, on a machine which simply failed to boot for
no reason that was clear. I can't recall the precise set of steps I went
through, but at one point I was offered a repair, and accepted the offer.

What followed was a Vist a install process which is pretty lengthy--an hour
or more, and opaque--very little indication of what is happening.

However, at the end of it all, everything was perfect--apparently exactly as
it had been before whatever event initiated the problem occurred.

See if you can wait maybe until tomorrow morning? That would give me a
chance to research the error a bit more --sometimes there's an unofficial
fix that work. And, I'd like to find an article describing the reinstall
process for Vista. For XP, there were some gotchas--and I'd like to be sure
the same is not true for Vista.
