That's just a child-safety feature that prevents you from running unsigned software. You can click on
More info to reveal the
"run anyway" button. You are likely to get this error when the release is still new and hasn't yet been reported and marked as safe by a multitude of users.

You can check the
SHA-256 hash or the
PGP SIGNATURE if you're worried about man-in-the-middle or server-side tampering.

That said, as long as you have downloaded the *.msi from our official website, you can generally trust the installer and run it regardless of the false-positive warnings from
Microsoft Defender SmartScreen and friends may give you.
