is not compatible or contains an error..

Try this. Go to Start Menu\Programs\Accessories and right-click on Command
Prompt. Choose "Run as Administrator". Then type the command:

sfc /scannow

Press enter on your keyboard.

The System File Checker scan may take awhile; this scans all system files.

You could also type the command:

sfc /SCANFILE=C:\Windows\AppPatch\AcLayers.dll

This gives a report, or tries to repair, that particular file.

Thank you for that dean-dean
done the scan and it said found some corrupted files but could not resolve
them..
any idea what else i can try now?
thank you

When you type just this command:

sfc /SCANFILE=C:\Windows\AppPatch\AcLayers.dll

does it say there were "no integrity violations found" or does it say that
there's an error?

no it just says scan finished,windows protection found corrupted files but
cannot fix them

Try this. Open Control Panel > Windows Update. Click on "View update
history". Is there an entry "Update for Windows Vista (KB935280)"?
If there is, go back to the main Windows Update window and click on
"Installed Updates" (on the left-hand side of the window, at the bottom),
and remove "Update for Microsoft Windows (KB935280)" (only). Then go here:

http://go.microsoft.com/fwlink/?LinkID=88379

Download and install the appropriate Package for your computer.

If that update is not listed in "View update history", then just go to that
page and download and install the appropriate Package for your computer.

hey mate..
did as u said at the end is said acces denied..error 80070005
its driving me mad..
norton finaly was updating and it worked..but windows update and windows
defender still wont..and i still get that error message about apppatch
folder..

 

[dean-dean]

I'm not clear at what point you got the "acces denied error". Did the
message occur when you were trying to uninstall the update? Is "Update for
Windows Vista (KB935280)" listed in your "View update history"?

link..it downloaded fine but at the end it said acces denied..error 80070005
