Where can I download SP2? I have this problem: Procedure entry point EncodePointer could not be located in kernel32.dll, but I first have to install SP2 before I can install SP3. No, computer is not connected to the internet so I can't use Windows Update.
You can download the Windows XP Service Pack 2 Network Installation Package from Microsoft here. FYI, it is 266MB so bring a USB drive or blank CD if you are going to move it from another computer.
Also, the Service Pack Center is where you can find the latest, as well as older versions, of service packs for your particular version of Windows.
