Vista - Impossible to install new Windows security Updates (error 800B0100 and 80246007)

Hi,

I am working on a PC Vista x86 and never had such a problem. For the last month now, I have not been able to install the following updates: (KB 968389, KB 956744, KB968816, KB970653, KB967723, KB970710, KB973540, KB948465).

Have also try to install them manually but it still does not work. I have SP1 on my PC.

I have tried many things (thanks to other forums...including installing KB947821) but nothing has worked yet.

Any help with this will be much appreciated.

Try install SP2 (KB948465) in safe mode.

EDIT
I'm sorry -I didn't notice Readiness Tool you've tried already

Run cmd.exe with administrative previlliges (right click on cmd.exe) as admin and type:

sfc /scannow

When it finish type in cmd.exe

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >%userprofile%\Desktop\sfcdetails.txt

on your desktop appear sfcdetails.txt

Download firegenul http://www.altairtech.ca/FireGenUL/download.asp
place firegenul.exe in C:\Windows\System32

next again run cmd.exe with admin previlliges and type:

firegenul

it creates report from WindowsUpdate.log and is stored in C:\Windows\System32 as FireGenReport.htm

Both FireGenReport.htm and sfcdetails.txt pack and attache to post

Thanks, please find reports attached.

Firegen reports many these errors:

and

These errors suggest CBS key corrupted or files in C:\Windows\Servicing\Packages.It may turn out Repair Install will be necassary.

Find CBS.log in C:\Windows\Logs\CBS

pack it and attache here,if it will be too big to attache host it on Speedy Share - upload your files here

EDIT
Question about KB947821:
You can't install it or only didn't help? This is difference.Even this tool don't help it create CheckSur.log report in C:\Windows\Logs\CBS.If you have this file attache to post also

Ok, here are new logs. Thanks.

Your checksur.log is interesting.

It reports about missing a few components in C:\Windows\Servicing\Packages

But also many files relate to KB948465 for example

...but KB948465 it is Service Pack 2 but you tried install it !From only CheckSur.log I can think you have already installed SP2 with corrupted some components.Can you clarify this?Do you have installed SP2 or not?

Independly from answers I'll attache here missing files,but due to I have them extract from SP1 and SP2 ...and downloading both service packs take some times
You have to wait a while

OK.At last I correct extracted files from service packs.It turn out alone 7-zip can't correct extract all files but finally I did it.The only one disturb me this error

this file don't exist in SP1 or SP2,some systems don't have this file,but my x64 system have this equivalent for x64 (but not the same),none of my x32 systems have this file.
But follow to instructions from @nathdakiwi from MS Tech SP2 will not install, needs SP1, but SP1 is installed
It seems you can ignore this error.Following to his instructions which had similar issue (although not the same)

I attached to post almost all request by CheckSur files,download them and unpack anywhere

1.Navigate to C:\Windows\Servicing\Packages,takeownership of this folder and add your account to have full control
2.Copy my files to this folder -if you have already any file then replace it.
3.Remove your account from permissions to Packages folder
4.Restore ownership of Packages folder back to "NT Service\TrustedInstaller"
5.Install SP2 stand alone

Useful links:Take Ownership of file
TrustedInstaller - Restore as Owner
Folder Permissions

Thanks again for help.
Did all this. And then tried to install SP2. A pop up told me that I had to install SP1 before installing SP2...same problem.

And do you have installed SP1 or not?If not install SP1.If you have already installed SP1 the problem is with the error

As said I can't find this file in SP1,none of of my x32 systems with SP1 installed,I'll try find answer on this,you have to wait for few hours...

There are required files.I can't explain how I didn't notice it before in unpacked SP2 .This file is included to SP2 not in SP1 thus none of Vista SP1 have this file.Never mind.The same procedure as before:

1.Download attached files and unpack anywhere
2.Navigate to C:\Windows\Servicing\Packages,takeownership of this folder and add your account to have full control
3.Copy my files to this folder -if you have already any file then replace it.
4.Remove your account from permissions to Packages folder
5.Restore ownership of Packages folder back to "NT Service\TrustedInstaller"
6.Again run SP2 stand alone
