Sonos update failed to download

"We found an update. Let's get Sonos runnning on the latest software." I click Update.

"The Sonos controller installer failed to download. Your controller did not update successfully. Please try updating one more time..."

So it sees that there's an update but it can't download it. Using Sonos Controlller for PC 11.15, Sonos OS is S1. Operating system is Win10 Pro. I have two speakers, both Play Ones.

I shut down my PC, rebooted my router, turned on my PC, plugged a play1 into an open ethernet cable, opened the Sonos S1 Controller program on my PC, it saw there was an update, I clicked Update and I still get the same “The Sonos controller installer failed to download” error message. Please advise.

Did you try to uninstall & reinstall the Sonos app on the Windows 10 machine?  Like I said mine usually tells me the update failed, but still works.  Also I no longer get the update available message.

    MoPac - Thanks for the reply. My S1 works fine without the update. I’m hesitant to delete it and reinstall in case I lose it. I’m slowly moving to my Win 11 system, so I’ll live with the download message.

    One thing to remember is most of your Sonos system exists on the Sonos hardware. The controller you use is only a method by which you interact with it, there is (almost) nothing stored in the controller. This allows you to have multiple controllers connected to the same system if desired, and all should show you the same data. It also means, as long as you use the ‘connect to existing system’ option when installing, there is no effect when deleting a controller. You’re always safe todo a delete and reinstall.

      I do not use the library function, but does this mean the Windows app is not necessary to index the library?

      Yes, all the ‘work’ is done at the system (Sonos device) level, the controller is just the display. If I recall properly, there was a need originally for the controller app to be installed on Windows machines in order for the Sonos system to be able to ‘see’ local (windows stored) files, but I think now that everything is SMB accessed, it is no longer the case.
