Airplay icon missing from iTunes on PC

Very disappointed with Marantz.  Should have been a lot better product / company.  Guess it's time to look around for something else and throw this thing on Craigslist or something. 

My Marantz 7004 isn't even supported anymore--only had it for 3 years--and the reviews that I have read for all Marantz streaming products are all caustic.  It's really sad that a company with their resources can't do basic networking

AirPlay runs through iTunes, guess it doesn't matter if PC or Mac.  This Marantz has been a pain in my butt since 2014.  They have issues with Pandora - can't use it for a month while they do security patches.  The Marantz is updated, their customer service is beyond the worst.  The Marantz is Wi-Fi.

Thanks for responding.  Eventually this will get sorted out...

Also...did you do a recent update on the Marantz?  I hada Marantz 7004 streamer, and it was buggy as all get up.  If you did a recent Marantz update and the problem started then, I would try to contact with Marantz (if you thought Apple support was bad...).  If you haven't done a recent update, then I would do so.  I am assuming that the Masrantz has an Ethernet or wi fi connection

PC, running Windows 10.  Any suggestions will be appreciated.

Thanks-

Is your PC a Mac or a Windows Computer?

Thanks, I will.

Hey there:  Thanks for taking the time to reply.

I have uninstalled and reinstalled iTunes.  When I tried the previous version iTunes could not read my library.  Also did as suggested on the Apple forum and unchecked the V6 in the file sharing, that did nothing.  I don't have Wi-Fi on the Marantz of my PC.  I am stumped.  Any other ideas/suggestions will be appreciated.

Better idea... is your wifi turned on? (look for the icon)
If it is on, maybe iTunes isn't connected to your network.

You could try to uninstall iTunes, then download the same version or the previous version. (Backup your music files)
