couldn’t get it to download let alone install

Bought the app but its stuck in the downloading stage(gray app in launchpad) I restarted my computer to try again then it did it again 5 times tried to download it on another computer and it still does it I think its not compatible with the computers because the internet speed is xfinity blast so it shouldnt have a problem downloading but it is. it was a dud for me I think the computer may not be compatible but it says it is.
