Windows 7 32 bit for us as well. I uninstalled flash completely in a bid to force it to use HTML5 but no such luck it just came up with a black screen then instead of the message we are all getting now which is:
“The Adobe Flash Player is required for video playback.”
Good Morning! So here’s the current situation for me:
Thanks for your advice @Peter. I’ve re-imaged one of our Intel NUCs with Windows 10 64bit build, installed the 1.8.2 client and connected it to our 1.8.0 server in our Docker test environment. Set the default layout using the aforementioned YouTube link and everything works seamlessly.
Because the latest client would not be accepted in our live environment (1.7.4 server) I kicked down the client to 1.7.9. This also works seamlessly. I’ve left it running since Friday afternoon (30th June) and there are no error messages, it hasn’t frozen or stopped working. Great!
So the only noticeable thing to change here is upgrading our operating system to Windows 10. Now that we have a working solution, I will seek to upgrade all NUCs to Windows 10 so that if we decide to stream anything from YouTube on any device, we will not have this problem.
Thank you @executiverocker for raising this issue and thank you bobdigby for your invaluable contribution (sorry, only 2 name mentions allowed for newbies like me!).
Thank you for the details @Karl, it’s interesting, so it would seem that it actually is Windows 7 that is affected by this…I do wonder if there were any recent updates in W7 or in YouTube that are responsible for it - I’m afraid as it is we can’t really do much about it - other than suggest upgrade to W10, which might not be suitable for everyone.
I agree with you completely @Peter. It is hard to pinpoint the actual fault. I did notice that there was an Adobe Flash Player update prior to this issue but other than that I cannot tell what other factors may have been at play. Strangely enough, one of our W7 setup has been behaving itself since 9 this morning. Very weird!
The issue fixed itself some time on Friday. I wonder if Youtube had been tinkering with something their end.
So @executiverocker, all of your players are working as normal? In the meantime I think I’ll check the rest of mine dotted around the place. Thanks for sharing that.
Yep! All suddenly came back into life! Nothing changed our end…
Well then, I’m glad to hear that, it would seem that YouTube indeed made some changes (or some update to W7 in the meantime), in any case, I’m glad that it works for you now.
Yes mine is working again.
Thanks everyone
EDIT seeing as I’m only allowed to enter 3 posts on a thread as a new user
Yep exactly the same! O no YouTube strikes again.
I have not tried anything yet has anyone else found a fix?
Cheers
Anyone elses broken again?
As its near the end of term I’m just going to leave it I think and see if it resolves itself like last time.
Waow!! Snap, snap and snap again!!! @executiverocker: now it’s the browser that’s at fault! What is YouTube doing??? I have the same issue - saw it yesterday. That was on a W7 machine. I’ve just tested it on a W10 machine and (like in previous posts) it’s absolutely fine - yey!
YouTube might resolve it by the time term starts again. They might orchestrate another incident again. Who knows. But from where I am, we are in a position to upgrade.
I hope you have a solution in place. Thanks for posting again. 
No luck here since the start of term just the wheel of death, any luck your end?
Hello @bobdigby. Everything is fine here. Where we are streaming, we are using Windows 10. My superiors are considering streaming from a different source (i.e. not YouTube).
Nope, still knackered when using a windows 7 machine. Great.

Looks like it’s all over for Youtube embeds on Windows 7.
I see, that would indeed mean YouTube embedding will work on W8.1+ only.
While it’s unfortunate to all Windows 7 users, it’s certainly good to know why it suddenly stopped working.
Hi ,
FYI, i already play youtube video using XIbo Player for Windows,
And as far as i know if we using Xibo Player For Windows, it was based on .Net.
Regarding to development progress on youtube,
and after i made several testing , it seems Xibo Player when playing Youtube need some of part IE 11 library
So … perhaps if you can upgrade your IE 8 to 11 on windows 7 , maybe it’ll be works
Thank you
Cheers for finding the page though
