Scrivener 3 installer will not open on macOS High Sierra

See title. I double click the .dmg installer and nothing happens. Have tried downloading again, same issue. I’m not sure what’s going on here and I’ve been unable to find anyone else having the same issue.

Hm, no idea. Do other DMG files open? Does any error message show up?

Have you restarted your Mac?

Also try clearing your browse cache before downloading again. Try downloading using a different browser.
