Flash player 11.8 does not play YouTube video Windows 7 Enterprise

Since I spent days troubleshooting this, I thought I might save others the same.
Environment:
windows 7 enterprise 32 bit (System meets requirements for flash player)
Workstation part of an AD Domain
Occurs on all workstations
Using a proxy to access the internet (this is not the problem as chrome works fine and HTML5 works fine)
Flash Player 11.8
Browsers: IE 8, IE9, IE10, FireFox, Chrome
Chrome plays videos fine
HTML5 Player plays fine in all browsers
IE8, 9, and 10 do not play videos; it starts to play then loops then dies with youtube error message
FireFox does not play youtube videos same as IE
I tried all solutions found on the internet, adjusting browser settings or uninstalling and reinstalling flash none of it worked.
solution down grade flash player

"Chrome plays videos fine
HTML5 Player plays fine in all browsers"
Chrome has its own embedded Flash Player - the installed version DOESN'T affect it.
HTML5 DOESN'T use Flash (It's MP4 or webm)
Download the Flash Player uninstaller. Flash Player uninstaller
Download the Adobe Flash Player installer directly by clicking the following links.
Flash Player for ActiveX (Internet Explorer)
Flash Player Plug-in (All other browsers)
SAVE all files.
On each workstation:
Run the uninstaller to remove both ActiveX and regular Flash Player.
Reboot and then run the installers to replace both plugins.
Check to be sure FP is enabled for IE: http://forums.adobe.com/thread/885448

Frostbitblue,
in Safari’s Preferences, select its Security tab, and make sure that its “Internet plug-ins: Allow Plug-ins” checkbox is checked.

Flash player freeze a lot when playing Youtube videos fullscreen from Linux, but plays videos ok from Windows (CPU: AMD APU).
When playing video in default size it's OK (windows and Linux), but when setting video in full screen, on Linux there's troubles: video is hashed (freeze every 3 seconds).

Hi s, well congrats on getting your brother's computer up and running. On your system, you have all correct Flash Player
files for IE and FF, as well as the SWO and SWF.
Since the Install of Flash Player, have you installed any programs that would have added any ActiveX Controls, or any other add ons or plug-ins?
Have you had an opportunity to see if your brother's computer has the issue you have when watching the same websites?
Are you using any ad-block in FF(Firefox) or any pop up blocker software installed? I can't imagine updating to FP version 10 alone would cause this.
Is this happening only on the BBC website? Does what you watch come thru the BBC website or youtube directly?
We have your brother's computer to use to determine what is going on. If he is able to see the BBC website and what you
are having problems with, then we can rule out the website.
Other browser add ons, anti-virus programs, etc. affect the browser. Even tho, no problem with vs 9. Sometimes updates
can have an affect, even with Windows as we all know:-)
Thanks,

Safari Does Not Play Youtube Videos

Hi,
I updated safari to the latest version (6.1.2) on my MacBook Pro (10.7.5) and now it does not play any Youtube videos at all. All I get is a black space instead of a video - neither video nor audio.
Does anyone know how to resolve the issue?
Best,
maybug

Go step by step and test.
1. System Preferences > Other/ Flash Player > Advanced > Delete All
     Press the "Delete All" button
     Install Adobe Flash Player.
    http://get.adobe.com/flashplayer/
    Follow the prompts. Quit Safari.
    Restart computer. Relaunch Safari.
2. Allow Plug-ins
    Safari > Preferences > Security
    Internet Plug-ins > "Allow plug-ins"
    Enable it.
    Press " Manage Website Settings" button for more options.
3. Check whether you are currently in YouTube HTML 5 trial.
     http://www.youtube.com/html5
    At the bottom left of the page uncheck the box beside
   "You are currently in the HTML5 trial".
4. Reset Safari.
    Click Safari in the menu bar.
    From the drop down select "Reset Safari".
    Uncheck the boxes beside all items.
    Check the box beside "Remove all website data".
    Click "Reset".
5. Turn off Extensions, if any.
    Safari > Preferences > Extensions
     Now try YouTube.
Best.

Safari in 64-bit mode on Snow Leopard does not play YouTube videos

Recently Safari stopped playing youtube videos while Safari is in 64-bit mode. The entire page renders correctly; however the area where the video is supposed to play remains a black box without controls. I can watch video from other sites, or I can watch video from youtube if I use another browser like firefox. Additionally, I can go to the youtube video owner's channel and view videos there just fine. It's only when I try to view videos that use the "http://www.youtube.com/watch?v=" method of displaying a video using Safari in 64-bit mode that it fails to play -- it plays fine with Safari in 32-bit mode.

@Annorax64: are you sure the problem is limited to the latest Flash Player? I'm pretty sure I was still running 10.1 when I first saw it, after getting an error "Safari Flash Player (Safari Internet plug-in) quit unexpectedly."
Upgrading to 10.2 didn't help.
It's not !. Flash player 10.1 is no better (as you can verify by downgrading here http://kb2.adobe.com/cps/142/tn_14266.html)

IPad does Not Play Youtube Videos

My iPad 2 dont loads YouTube videos, or it's really slow going. I tried many tips from the Internet, but nothing works for a long time. Will it give a update of ios or will I stuck in this sh**?

If they are Flash based, which a lot of Youtube is, they won't play.
Try using the Youtube app instead of trying to play through Safari.

Answers in this forum have shown different things have worked for different people.
For some clearing YouTube cookies and the cache solved the problem. For details of how to do that see https://support.mozilla.com/kb/Deleting+cookies and https://support.mozilla.com/kb/How+to+clear+the+cache
Others had to go a step further after deleting YouTube cookies and block YouTube from saving cookies. In the Tools menu select Options to open the Options window. Go to the Privacy panel and make sure it is set to "Use custom setting for history". Click the Exceptions button, type in http://www.youtube.com and click on Block
Another option is to disable hardware acceleration for Flash. To do that right-click on a Flash video, select Settings, go to the first tab of the settings for the option to enable/disable hardware acceleration for Flash. This is something recommended by YouTube for those having problems - http://www.google.com/support/youtube/bin/answer.py?&answer=1209379

Flash player plug-in does not work

flash player plug-in does not work

You don't say on what Mac, and you haven't actually asked a question, but perhaps this might be helpful:
The latest version of Adobe FlashPlayer can be obtained from here:
http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFl ash
You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS. Note that version 10,1,102,64 is the last version available to PPC Mac users*. The latest version, 10.2.152.25 or later, is for Intel Macs only, as Adobe no longer support the PPC platform. Note that the latest Flash Player update only works on YouTube with Safari in 32 bit mode - until YouTube correct this.
* Unhelpfully, if you want the last version for PPC Macs, you need to go here: http://kb2.adobe.com/cps/142/tn_14266.html and scroll down to 'Archived Versions/Older Archives'. The first one on the list, Flash Player 10.1 is the one you download. More information here: http://kb2.adobe.com/cps/838/cpsid_83808.html
You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb2.adobe.com/cps/865/cpsid_86551.html#prob1=uninst,os=m10.6,
and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.

I have checked all of my permissions and contiue to get this message after 68% mark when trying to install Adobe flash player. User does not have sufficient privileges to install adobe flash player. A required file (C:\windows\syswow64\macromed\flash\flas

Flash player 11.5 does not open background pictures of my website

Flash player 11.5 does not open background pictures of my website scilang.com as well as many others'. 11.4 is ok. However, 11.5 has really messed it up.
I tried it with IE9, Chrome, Firefox. No. No with Flash Player 11.5. Why are such things happening all the time?

I can't comment publicly on dates for future releases, sorry.
For users that have selected "Allow Adobe to Install Updates" during installation, they will automatically get the update as soon as it becomes available. There is some lag in uptake in general (we're really only about halfway into the adoption curve for Flash Player 11.5), so the problem won't be resolved overnight. If you have access to the source, you may want to update your content temporarily to work around the issue. If it's just a generic slideshow, you might want to consider replacing it with an AS3-based alternative. Lightroom distributes a nice flash-based slideshow, for instance.
There are a couple actionscript-based workarounds you can implement in your content until the next Flash Player 11.5 maintenance release has been deployed to the general release audience.
There's one workaround here:
http://forums.adobe.com/message/4841531#4841531#4841531
The root of the issue is that the onEnterFrame event isn't getting emitted by MovieClips that embed JPEGs in ActionScript 2 content. This was an unfortunate side-effect of an unrelated graphics optimization. We have tests that check that onEnterFrame is emitted, and that JPEGs are rendered, but not one where we confirm that a SWF embedding a JPEG emits an onEnterFrame event. Because the change was isolated to AS2, we didn't see it in our manual URL testing either, as that testing tends to focus on the most popular sites on the web, which usually host newer AS3-based content. We've added tests to cover this case to prevent it from breaking again in the future.
Anyway, apologies again for the inconvenience. Hopefully this information will help you workaround the problem until the next update goes out.

Hi Mohan_111
Thank you for posting and welcome to Nokia forum!
Things to try:
1. Uninstall and reinstall the Youtube downloader.
Restart your phone
1. Press and hold the power button until the phone vibrates and switches off.
2. Switch your phone on again.
Reset the settings
Restore the original factory settings (Menu > Settings > Phone > Phone management > Factory settings > Restore). This reset will not delete any data on your phone it will just restore the settings back to default state.
Update the software
Make sure your phone is running the latest software. Use Nokia Suite to update or reinstall the phone software.
