Anything CAD related.
AutoCAD comes to mind first, but Siemens NX (Unigraphics) existed before and is still currently sold. Dassault CATIA is another CAD software older than 40 years.
PTC Creo (Pro/E), McNeel Rhino 3d, Dassault Sold Works, Archicad, also are software packages with really long life spans.
You can also include plugins and support tools such as simulation modules, and render plugins. Many of which have been around for 20+ years, but are too numerous to list.
