Something goes wrong when I upload the theme file

I just downloaded this jollyall theme: https://www.mojomarketplace.com/item/jollyall-multi-purpose-wordpress-theme

I went to upload it onto my site and the documentation says to upload a zip file called macho.zip — documentation here: file://localhost/Users/sarahpeller/Dropbox/Backups/Clients/Current%20Clients/Samantha%20Sweetwater/Website/Themes/wordpress-doc/index.html — but there is no file of the sort. But I did find a zip file called “jollyall-v1.0.0.zip” that, when unzipped, contains all of the theme files as far as I can tell. But when I try to upload it, I get that “something went wrong, try again” error.

What’s going on? Anyone know?
