Hello again, and sorry for the late answer.

I'm using the Itch app on Arch Linux, and I let the app manage the install. The error message I'm getting is "no executable found".

Hi there! 
This is a know issue with the Itch store. I recommend installing it from the website, not the steam like itch store app. Several softwares will give you problem when installed through the store.
