Error when trying to download on Mac

Hi, I’ve been trying to download Insurgence and I’ve downloaded up to Step 5, where it attempts to download Wine Crossover but I keep getting the following message:

==> Installing Cask wine-crossover
Warning: macOS’s Gatekeeper has been disabled for this Cask
==> Moving App ‘Wine Crossover.app’ to ‘/Applications/Wine Crossover.app’
==> Linking Binary ‘appdb’ to ‘/usr/local/bin/appdb’
==> Unlinking Binary ‘/usr/local/bin/appdb’
==> Backing App ‘Wine Crossover.app’ up to '/usr/local/Caskroom/wine-crossover/2
==> Removing App ‘/Applications/Wine Crossover.app’
==> Purging files for version 23.7.1-1 of Cask wine-crossover
Error: It seems there is already a Binary at ‘/usr/local/bin/winehelp’.
Something went wrong while installing Insurgence…

Has anyone encountered anything similar or be able to help me?
