By 2004, Protel had already moved away from the classic DOS and Windows 98 interfaces. DXP (Design Explorer) was the awkward teenage phase between the simplicity of Protel 99 SE and the modern ribbon interfaces of Altium.

SP4 (Service Pack 4) was the holy grail. It was the version where things actually worked. The autorouter was decent, the schematic capture was snappy, and the integration between SCH and PCB didn't require a blood sacrifice. So, when the torrent appeared, the community rejoiced.
Before cloud storage and direct downloads, we had BitTorrent. Searching for Protel Dxp 2004 Sp4.torrent on IsoHunt, The Pirate Bay, or Demonoid was a rite of passage.
