I've tried repeatedly to install MSE but keep getting Error Code 0x80070643. I think I've tried everything that applies to my problem from this search (https://www.google.co.nz/#q=error+code+0x80070643).

I'm running Windows Vista Home Premium SP2.

Can anyone suggest anything else I can try? I hate being without any form of Internet security.

Thanks.

You could try this (http://answers.microsoft.com/en-us/protect/forum/mse-protect_start/mse-installation-failure-with-error-code/6e32fbe4-da39-460b-b27b-05018c937a39)



I did this and it fixed the problem:

1. Uninstall Microsoft Security Essentials.

2. Download and install Windows Installer Cleanup (http://support.microsoft.com/kb/290301)

3. Use the Windows Installer Cleanup to uninstall Microsoft Antimalware.

4. Open regedit and look for HKLM/Software/Microsoft/Microsoft Antimalware. If it's still there then remove it.

5. If you have problems removing the registry entry then you need to take ownership and permissions to delete that entry.

6. Try to install Microsoft Security Essentials.

Considering Microsoft don't even recommend it anymore, why bother?

Do your own research re keeping with MSE. There is no AV program that will stop everything all the time, especially when the user approves the installation of the baddies!

You also need to assess the affect on performance of any AV program/suite..

hi Greg
had a similar problem a while back and this fixed it for me
1. Quit all Windows programs.
2. Click Start, type Run in the Search box and then press Enter, type msiexec /unregister in the Open box, and then click OK.
3. Click Start, type Run in the Search box and then press Enter, type msiexec /regserver in the Open box, and then click OK.
4. Restart your computer.

urban myth I think.
But otherwise a valid point, why bother, especially if its giving install issues .;)

Microsoft has admitted Windows users should install antivirus above and beyond its own Security Essentials, describing its protection as merely a "baseline" that will "always be on the bottom" of antivirus software rankings

----------- < snip >

Holly Stewart, senior program manager of the Microsoft Malware Protection Center, told Dennis Technology Labs that Microsoft made a decision to switch to what it calls a "baseline strategy".

"We had an epiphany a few years ago, back in 2011, where we realised we had a greater calling and that was to protect all Microsoft customers," she said. "But you can’t do that with a monoculture and you can’t do that with a malware-catching ecosystem that is not robust and diverse."

Don't think any of the other AV programs are any better. They're probably worse than MSE (they may offer better protection, which I doubt), or they'll crash more often

Altho I havent tried Eset. So, I dont think it'll matter what you install. Depending on what you do online and where you go, you're going to get infected whether you like it or not

Where are the Official statements from MS stating this, not just a report of what someone may have heard/misquoted
From that link above
"The usual misinterpetation of reporters

I suggest you read the following blog post from MS where is stands behind its AV software:"

Avast is free and ok, it will try to install chrome if you let it though.
One worry regarding this and your other thread is that some malware blocks the installation of programs, especially MSSE.

How recent are these problems? it might be worth trying a system restore. Also maybe try the Eset free online scanner.

Looks like you can get this error if some antispyware / AV program is still on the system too. Looks like a rootkit can also cause this error, and stop MSE from installing. Get tdsskiller run it, if it finds anything select cure then reboot

Thanks for all the suggestions - tried them all to no avail. I'm having other quirky problems eg can't install my scanner drivers, so although It's quite a hassle I'm gonna format and reinstall Windows.

personally I prefer MSE as I witnessed it clean virus's that other so called top of the line commercial virus checkers haven't even detected ie the FBI virus and its variants, but as we all know every virus checker has a weakness and the only true prevention is dont turn your pc on, Now where's the fun in that.

Every antivirus software will at some time find viruses that the others haven't (yet). And some just happen to be better than others.

But since a standard AV is always one step behind the virus writers (The virus must first be released and infect some people before it is detected and added to signature files) they are still not the best, even with heuristics. Which is why I like Comodo's Defense+. I whitelist known good programs and default block everything else. And of course I run a traditional AV too.
