Well, I think the 32-bit version is still the "official" release, so grabbing it from the official location, perhaps? But it won't work on Catalina, so if you've upgraded your Mac, you're stuck.
I have plans to put HL inside a virtual machine running Mojave so it'll be useful into the future. (You can call me paranoid, but if the LW servers stop validating licenses, I want to continue to have a working application.)
