i have vista, and trying to update windows, and I also keep getting a message
that the windows installer can not be accessed. i went through the steps that
i found on this site and it still did not work.

Again, which updates are being offered that you aren't able to install?

Is this a sudden, new problem or an ongoing one? In other words, have you
ever been able to install updates on this Vista machine?

Tip: Temporarily disable real-time protection by your anti-virus and/or
anti-spyware applications (e.g., CounterSpy, Spysweeper, Spybot, AVG
Anti-Spyware) and/or any third-party firewall (e.g., ZA) before attempting
to install the update(s).

Sorry this is no help, but I'm getting the same, so if you get/have an
answer, please let me know.

I HATE vista. I'm particularly annoyed right now at the way MS thinks
it can take over my machine whenever it sees fit, no matter what I'm
doing and how important it is, and launch an update download that swamps
the whole thing. That I don't need right now, if ever.

Yes, I know I can turn this auto update off, but the damn thing still
downloads - it just doesn't install. And then it persists in telling me
that auto update is turned off, as an error. It's NOT an error, it's an
INSTRUCTION! And now it doesn't even work.

Message for MS: this is MY computer, not yours. I will decide what goes
on and when, not you. And if you're going to send me this stuff, then
for God's sake make sure it works.

I want to decide when I download and install updates to your overblown
O/S, not you. I'm busy.

Automatic Updates downloads shouldn't swamp the system, in fact they're normally
invisible.  Do you mean the computer starts running very slowly, or that your
internet connection overloads?


You can configure it to notify you and only start the download when you approve
it, or you can turn it all the way off if you want.


I believe you can turn this warning off as well, but as I'm not using Vista I'm
not sure how to go about it.  Someone else may be able to provide specific
instructions.

Double Check to see that Windows Update service and Windows installer
service are both Automatic and Started. I have an issue with Vista
sometimes changing my Windows Backup settings somehow and i have to
reset them in order to run my daily backup. Turns out in this case it
shut off Windows Installer. To make sure its running go to: Control
panel > System and Maintinance > Administrative Tools > Services.
This Should Solve the issue.

Does not match your error exactly - but likely would fix you up.

At this point - if the machine was mine - I would follow these directions:
http://social.answers.microsoft.com/Forums/en-US/vistawu/thread/ea20ba99-017e-4ae0-975b-1ef8b771dff8

In other words...  Use the .NET Cleanup Tool (Method 2), reboot and install
the .NET Updates in this order:

- .Net Framework 3.5
(http://www.microsoft.com/downloads/details.aspx?familyid=333325FD-AE52-4E35-B531-508D977D32A6)
- .Net Framework 1.1
(http://www.microsoft.com/downloads/details.aspx?familyid=262D25E3-F589-4842-8157-034D1E7CF3A3&)
- .Net Framework 1.1 SP1
(http://www.microsoft.com/downloads/details.aspx?familyid=A8F5654F-088E-40B2-BBDB-A83353618B38&)

Should be good to go.

Needs repeating in full?
When installing updates using Windows update or Microsoft Update you may
receive Error 0x643 or 0x80070643 (23 Oct-09)
http://support.microsoft.com/kb/976982

=====================

Step #1 => Before doing anything else, write down what .NET Framework
versions are currently installed:

How to determine which versions of the .NET Framework are installed and
whether service packs have been applied
http://support.microsoft.com/kb/318785

Step #2 => Now see Resolution Method 2 in this related KB article...

When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0,
or 3.5, you may receive Windows Update error code "0x643" or Windows
Installer error code "1603" (ignore the title, if need be)
http://support.microsoft.com/kb/923100

After running the .NET Framework Cleanup Tool, reinstall all .NET Framework
versions (but only the ones you wrote down in #1 above) manually using the
download links on the page then run Windows Update manually to install
security updates for same.

NB: If you remove .NET Framework 3.5 (SP1) using the tool, reinstalling .NET
Framework 3.5 will also install .Net Framework 2.0 SP2 and 3.0 SP2; then
Windows Update will offer .NET Framework 3.5 SP1.

IMPORTANT! => If you remove .NET Framework 3.5 (SP1), reinstall your .NET
Framework versions in the following order:

1. .Net Framework 3.5, then...
2. .Net Framework 1.1, then...
3. .Net Framework 1.1 SP1

NB: KB923100 references this page:
http://blogs.msdn.com/astebner/archive/2006/05/30/611355.aspx.  Please read
ALL of it as well as the related page
http://blogs.msdn.com/astebner/pages/8904493.aspx before using the .NET
Framework Cleanup Tool.
