The original World of Warcraft clients version 3.3.5a and older don’t have support for 64 bit, so they are only available in 32-bit executables. There is no WoW.exe 64 bit for WOTLK 3.3.5 and older versions.

This could be an issue if you are running macOS Catalina or macOS Big Sur (or newer) since Apple removed the support for 32 bit programs since Catalina.

Luckily there is a way to run 32-bit applications on macOS that works for WoW clients version Wrath of The Lich King (3.3.5a), The Burning Crusade (2.4.3) and Classic (1.12.x).
