Short answer: No, not officially. YoYo Games no longer sells or supports Game Maker 8.1.
Longer answer: If you already purchased a license back in the day, you might be able to re-download the installer from your old YoYo Games account (if it still exists). However, even then, the Pro features may not unlock without offline authentication workarounds – which are not officially supported.

Game Maker 8.1 / 8.0
Game Maker 8.1 was discontinued years ago. YoYo Games, which later became part of Opera, stopped selling licenses for version 8.1 around 2012–2013 when they released GameMaker: Studio.
