Sure - another one that thinks that switching platforms (in any direction)
will resolve all their problems. Please - do switch. Sometimes it works
out for the switcher, most of the time it just presents itself in the form
of new problems with fewer friendlier resources than previously to turn to
and more money spent/more time spent. It doesn't matter if you started at
the macintosh and are deciding to switch to windows or started at linux and
are deciding to switch to windows or started with windows and decided to
switch to macintosh - usually the change is worse than the solution to
*your* problem would be. ( There in-lies the actual issue - seldom does
anyone come to the conclusion that the problem is with their
system/something wrong there and not some overall conspiracy of the
OS/software companies to keep them from working/playing as they want to.
;-) )

So here you are - and in your rant you only really gave two bits of
information (accidentally I would say) which are in the subject line (error
80070490) and the fact that you have Vista (sort of mentioned 'in passing').

Based off that - not much to do but give it a shot. So - let's go through
your problem *if* you are wanting to fix it.

You should get the edition and version information...

Start button --> RUN
(no "RUN"? Press the "Windows Key" + R on your keyboard)
--> type in:
winver
--> Click OK.

The picture at the top of the window that opens will give you the general
(Operating System name and edition) while the line starting with the word
"version" will give you the rest of the story. Post _both_ in response
to this message verbatim. No paraphrasing - instead - ensure
character-for-character copying. That's the edition (in the top picture)
and the exact version number in detail (the 'version' line.)

What version of Internet Explorer are you currently using? Easy to find
out. Open Internet Explorer and while that is in-focus, press and hold
the "ALT" key on your keyboard. With the "ALT" key still pressed, press
(just once, no holding) the "H" key. Now, with the "ALT" key still
pressed, press (just once, no holding) the "A" key. That will bring up
the "About Internet Explorer" window. It will give you the exact version
you are using - repeat what you see there in response to this message.

How to determine whether a computer is running a 32-bit version or
64-bit version of the Windows operating system
http://support.microsoft.com/kb/827218

What AntiVirus application are you using? (Name and exact version, please.)
- Was any flavor of "Norton" products ever installed?
- Was any flavor of "McAfee" products ever installed?

Do you have a third party firewall - or are you using the built-in Windows
firewall?

Do you ever run any antimalware applications? If so - which ones and when
did you scan with them last (full scan, not quick)?

Some stuff you can do... In order (may seem like quite a bit, but you let
the
machine get into quite a state, this should clean it up.)

Reboot so you start with a fresh machine. For everything here you will
need to logon as an user with administrative (installation) priviledges.

Download/install the "Windows Installer CleanUp Utility":
http://support.microsoft.com/kb/290301

After installing, do the following:

Start button --> RUN
(no "RUN"? Press the "Windows Key" + R on your keyboard)
--> type in:
"%ProgramFiles%\Windows Installer Clean Up\msizap.exe" g!
--> Click OK.
(The quotation marks and percentage signs and spacing should be exact.)

It will flash by *quick*, don't expect much out of this step to get
excited about. But the cleaner your machine is to start with, the
better your luck will be later (not really luck - more like preparedness,
but that's not as fun to think about, eh?)

Yeah - you will get tired of rebooting - but let's soldier on and reboot
again and logon as an user with administrative priviledges.

This time (and this is one of the more time-consuming steps) you will be
running (one at a time with a reboot in-between) three different
anti-spyware/anti-malware applications to ensure you come up clean.

Download, install, run, update and perform a full scan with the following
(freeware version):

SuperAntiSpyware
http://www.superantispyware.com/

Reboot and logon as administrative user.

Download, install, run, update and perform a full scan with the following
(freeware version):

MalwareBytes
http://www.malwarebytes.com/

Reboot and logon as administrative user.

Download and run the MSRT manually:
http://www.microsoft.com/security/malwareremove/default.mspx

You may find nothing, you may find only cookies, you may think it is a
waste of time - but if you do all this and report back here with what you
do/don't find as you are doing all of it - you are adding more pieces to
the puzzle and the entire picture just may become clearer and your
problem resolved.

Reboot and logon as administrative user.

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&)

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.

I would then check the hard drive(s) for errors and straighten things up...

Windows Vista CHKDSK:
http://www.windows-help-central.com/windows-vista-chkdsk.html

Windows Vista Defragmentation:
http://windows.microsoft.com/en-us/windows-vista/Improve-performance-by-defragmenting-your-hard-disk

Now - before checking for more updates - I would do something else, but you
have not yet provided your operating system details. So...

32-bit Windows Vista ______ Edition with No SP or Service Pack 1 or 2

How do I reset Windows Update components?
http://support.microsoft.com/kb/971058

.... and click on the "Microsoft Fix it" icon. When asked, select "RUN",
both times. Check the "I agree" box and click on "Next". Check the box
for "Run aggressive options (not recommended)" and click "Next". Let
it finish up and follow the prompts until it is done. Close/exit and
reboot and logon as administrative user.

64-bit Windows Vista ______ Edition with No SP or Service Pack 1 or 2

Download, install and run...

System Update Readiness Tool for x64-based Systems
http://www.microsoft.com/downloads/details.aspx?FamilyId=f6f353c0-d00e-43e7-97ef-0feefc7ff064

Reboot and logon as administrative user.

Now - after all that - try your updates again.

Come back and let everyone know if it worked out for you or at least provide
the requested information so someone might be able to help you further.

Now you might say that you have tried all of this before - but was it all at
once and all in the order given? If not - please - follow the directions as
given all at once ignoring whether or not you think/know you have done one
step before and/or you think you have done an equivalent step.

Worst case - after you do all this - you will still have a problem but a
much cleaner system and will have provided those here with something they
can work with instead of just waiting on someone else to fix the problem
with your system.
