32-bit windows can run the mod, all of the files for the 64-bit game are the same except for the .exe, which you will need from a semi-recent 32-bit version of the game. If you have a 32-bit version of the game from 0.5.24 to 0.5.25 you can simply copy the .exe into Aric's pre-merged version and it will work.
Macs require special setup to run mods (https://itch.io/t/628179/how-to-make-mods-work-on-mac-osx-without-wine), but so long as you have the OSX version of the game from 0.5.24 to 0.5.25 you should be able run Aric's pre-merged version with this setup.
If you lack one of those copies of the game from 0.5.24 to 0.5.25, then I would recommend googling the terms "strive for power 0.5.25 download" (this approach works for a frightening number of things). I saw a copy at lewdzone, no idea if the links work.
