If you are trying to update Windows XP to SP3 you may get an access denied error. This access denied error shows up even if you run a standalone Windows XP SP3 download like the one at Microsoft. Sometimes this access denied error is caused by registery permissions however in my case it was an antivirus product with a feature called “Access Protection” which was preventing my install of SP3. By disabling the virus scanner and specifically the Access Protection feature I could install SP3 and then re-enable my scanner.
