.APK will not 'open' after install

[Android Central Question]

Galaxy s7 nougat. Trying to get live wallpaper 'Windy_weather,apk' to open. Installs no problem using Astro app manager, but when finished, only option is 'Done'. The option to 'OPEN' is greyed out. Have uninstalled another weather wallpaper, but still can't get Windy Weather to open. Yep, tried restarting phone - no luck. Samsung default wallpaper is all that is on main screen.
Any suggestions?

Welcome to Android Central.

Is this the app? https://play.google.com/store/apps/details?id=co.windyapp.android If so, how about installing from Play Store?
