service pack 3 ... access denied
I have been trying to install service pack 3 for xp and its gets so far and then it says access denied ... I first tried with the downloaded iso image and then I tried downloading the smaller service pack from Microsoft .... it goes right to the very end of the installation and then during the checking process both times I get access denied ... I was reading the other post about this and I have downloaded the subinacl file and have also copied and pasted the other stuff into notepad and saved it as "reset cmd " ... I have backed up my registry also .... from the other post I'm under the impression that I need to install subinacl and once that is installed then click on the "reset.cmd" ... do I need to do anything else ... could someone please list the exact steps for me ... both times when I did try to do the installation I took the computer offline, shut down windows defender and disabled my antivirus ... there is nothing else that I know of that could be running to prevent the installation ... I have spybot installed, should I uninstall that ... any help with this is greatly appreciated ... thank you
