If they see this warning:

This message doesn’t mean the file is harmful.
It appears simply because the app is new and not yet recognized by Microsoft. Once more people install it, the warning will disappear.
- Click “More info” (the small blue text under the warning).
- A new button will appear at the bottom: “Run anyway.”
- Click “Run anyway” to launch the installer.
We can’t wait for you to try it!
