Can't Install KB953297, error code 0x643

I can download but not install KB953297, I recently downloaded McAffee
VirusScan, think that has something to do with it. Any suggestions would be
appreciated. I use XP. Thank you.

Get rid of McAfee - go with something like Avira, Avast, AVG, NOD32, etc.

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. ;-)

Download, install, run, update and perform a full scan (separately) with the
following two applications (freeware versions are the ones to use for this):

SuperAntiSpyware
http://www.superantispyware.com/

MalwareBytes
http://www.malwarebytes.com/

After performing a full scan with one and then the other and removing
whatever they both find completely, you may uninstall these products,
if you wish.

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

Reboot.

Download/Install the latest Windows Installer (for your OS):
( Windows XP 32-bit : WindowsXP-KB942288-v3-x86.exe )
http://www.microsoft.com/downloadS/d...displaylang=en

Reboot.

and...

Download the latest version of the Windows Update agent from here (x86):
http://go.microsoft.com/fwlink/?LinkID=91237
.... and save it to the root of your C:\ drive. After saving it to the root
of the C:\ drive, do the following:

Close all Internet Explorer windows and other applications.

Start button --> RUN and type in:
%SystemDrive%\windowsupdateagent30-x86.exe /WUFORCE
--> Click OK.

(If asked, select "Run.) --> Click on NEXT --> Select "I agree" and click on
NEXT --> When it finishes installing, click on "Finish"...

Reboot.

Follow these steps...

After the cleanup, addressing your more direct issue (although the rest may
help with this and will not hurt anything):

Have you reviews the KB article associated with the update?
http://support.microsoft.com/kb/953297
(Specifically - the "Known Issues" section?)

I'd suggest:
http://support.microsoft.com/kb/923100/
Method 1.

Did you check you had the prerequisites covered (from the article above):
http://www.microsoft.com/downloads/d...9-54D056D6F9F4

Have you attempted to download, save and install the update manually for
your Operating System version/service pack level?
http://www.microsoft.com/technet/sec.../ms09-061.mspx

After doing all of that - have you used the "How to obtain help and support
for this security update" from the KB article?

"For home users, no-charge support is available by calling 1-866-PCSAFETY in
the United States and Canada or by contacting your local Microsoft

Come back - let us know if that helps!

I have Avast and still the update will not install. This is the text it gives me: The following updates were not installed - Microsoft .NET Framework 1.1 Service Pack 1 Security Update for Windows 2000, Windows XP, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 (KB953297)

To avoid confusion, please begin a new thread about your specific problems
instead of hijacking someone else's thread. State your IE version and full
Windows version (e.g., WinXP SP3; Vista SP2) in your first post.

You seem to have replied to an October 2009 conversation

I suppose you did the *first part* of the instructions I had given (reported
back your Operating system version/edition.)

Assuming you have the same trouble as the subject presents - have you
performed the steps given after those (or are you in the process of doing
so?)
