Trash it and download another one.

Get macOS Mojave.

If that doesn't work then try installing it in Safe Mode:

Delete the installer if it is sitting in your Applications folder"

"Install macOS Moajve.app"

Be sure to empty your trash, and try again.

If your download speed is in question—connect to a different Network and try again.

You're welcome. Safe Mode isn't for watching videos, it's for testing and temporarily working around problems. See "Some features aren't supported in Safe Mode" from the Support Topic.
