The Sena application for iPhone instructs the user to go to www.sena.com to download and install the Updater Software. I could not find any mention of "Updater Software" on the site. I searched for the term "updater" on the site and it returned no results. I finally found it using a generic search of the web at: The Best Motorcycle & Action Sport Bluetooth Devices | Sena. 
It worked perfectly in my case on a Windows 11, 64 bit pc.
The only frustrating part of the software update on my Sena SRL2 was the updater would continue to ask you if you want to update the software, even after the most recent version was successfully installed. I've seen this in other software and it is unnerving because even though the install process indicated a successful update it still asks if you want to update. 🤷♂️
The most current version of Sena Device Manager is: 4.4.16
The most current Sena SRL2 software is: 1.0.9
