Are you on windows? If your on mac, it won’t work. I just realized .exe files don’t work on mac lol.
Did you extract the zip? If you did, make sure you have the exe file with all the dependencies (dlls, imgs and more) then try running it.
It will come up with windows defender saver thing, just click “read more/more info” and click run anyway.
It will load and you can play. Don’t worry, there are no viruses. Search up buildbox and you’ll see.
