I am trying to install XP. This is what happens:
Installed XP. Okay. Reboot.
Installed SP1. Okay. Reboot.
Installed SP2. Okay. Reboot
Installed SP3. "Extraction Failed/File is corrupt"
I just used the SP3 file a couple weeks ago on another machine. I know it is not corrupt. To be sure, I retrieved another copy from a backup disk made before I used SP3 the previous time and it did the same thing.
