Problem installing Adobe Flash Plug in Update on Mac

Message says 'only a single instance of the program can run.' Online help says to hit 'ok' and another instance of the program will take over. We hit 'Ok'. Nothing happens. What do we do?

Trying to install Adobe Flash Player 11 on my Mac...PluginProcess?

Trying to install Adobe Flash Player 11 on my Mac. The insallation stops and I am told to exit something called PlugInProcess. I don't know what it is. I don't show it being open. Any help?

The Plugin Process is an app that runs alongside Firefox and Safari when they're open. Lately Firefox's plugin process has been "hanging" on my Mini. I'll close the app but it keeps running and using RAM for several minutes.
Download the Mac Offline Installer here
Quit your browser and reboot if necessary to "kill" all processes.
Then mount the DMG and run the installer.

Problems installing Adobe Flash Player 14.0.0.125.

Can not get my MacBook Pro 17" to install Adobe Flash Player 14.0.0.125. Our iMac installed it.
The system hangs forever looking for resources

Hopefully, you'll be installing the 14.0.0.145 Flash update very soon - however the same problem you experienced persists with that.
Fortunately there is a simple solution.
There appears to be a problem with Adobe Flash Player Install Manager - the simple answer is to let the system install the flash update instead:
When you use the Flash updater, it downloads a disk image to a temp folder (inside /private/var/folders but you don't need to know that). This is automatically mounted (briefly) while the app 'Adobe Flash Player Install Manager' launches. Adobe Flash Player Install Manager is supposed to manage the whole instillation but in some case it gets stuck. If this process fails for you (such as hanging on 95% completion), there is a very simple route forward which doesn't require you to open your browser or manually download anything.
It only requires 3 steps and you can be 100% sure you are getting the correct update - the one Adobe tried to install but failed. I've broken these down into detailed but very simple substeps (further down this post) for anybody who is unsure, but experienced users can probably just follow these three steps:
Force quit Adobe Flash Player Install Manager
Locate and mount the Flash Player Installer disk image with Disk Utility
Locate the Adobe Flash Player installer package within the Install Manager app and run the installation from Finder
Hope this helps. Enjoy.
Those steps in detail (as carried out in OSX 10.6.8).
1. Force quit Adobe Flash Player Install Manager
Press these three keys together: Cmd + Option (or Alt) + esc
Select Adobe Flash Player Install Manager in the popup window titled "Force Quit Applications"
Hit return or click the button labelled "Force Quit"
2. Locate and mount the Flash Player Installer disk image with Disk Utility
Open Disk Utility (in Applications/Utilities folder or find it with Spotlight)
On the left hand side, your attached drives and mounted volumes are listed above a horizontal line. Below that line you should see one or more disk images (named e.g. something.dmg). These are recently accessed disk images - including one containing the adobe updater.
At or near the bottom of that list you should see something called decryptedFile.dmg
Under that you might see a (greyed out) volume image called Flash Player
Double click decryptedFile.dmg (or the Flash Player volume if you can see it - it makes no difference).
This should mount a volume titled "Flash Player" and automatically open a finder window showing the contents.
The volume "Flash Player" will show up in your Finder sidebar and on your desktop (unless you've chosen not to show External Disks in Finder preferences)
3. Locate the Adobe Flash Player installer package and run the installation from Finder
You should by now have a Finder window open showing the contents of the volume "Flash Player". If not, open a new Finder window and click on Flash Player in the sidebar. The sole contents are an app called Install Adobe Flash Player.
Right click the item "Install Adobe Flash Player" and select "Show Package Contents" from the contextual menu that appears.
This opens a new window showing a folder called "Contents". Open it by double clicking to reveal the contents including a folder called "Resources".
Locate and open the folder "Resources" and look for a file called Adobe Flash Player (Adobe Flash Player.pkg)
This is the Installer Package for the update. Double Click it.
Don't be put off by the words "Welcome to the Adobe Flash Player Installer" - this is not the Adobe Flash Install Manager (the one that failed you earlier) this is Apple's "Installer" app.
Follow the steps to the end then eject the volume Flash Player in the normal way (e.g. Finder sidebar)
Open the Flash Player control panel to check the current version has now been updated.
Don't be put off by "PPAPI Plug-in is not installed" - you can ignore it.
Some steps may go differently if you are running a different version of Mac OS X - I use 10.6.8

Having problem installing adobe flash player 11.0.1.152 says close mozilla how do you do this

I have tried several times to install Adobe flash player 11.0.1.152. It keeps stating to shut off Mozilla. How do you shut Mozilla off?

"Ctrl+Shift+Esc" placing you into the Windows Task Manager, you need to be in the in the "Processes" tab to make sure that firefox.exe is no longer running -- if it is running then terminate it by selecting the use "End Process" button or from context menu. (That is a Windows 7 keyboard shortcut not in earlier versions of Windows)
There is a better way of ending Firefox, but it is too late for you to close firefox properly. Full set of directions to check and update flash.
Make sure you are starting in the correct place for Flash

If you want to read PDF files in you browser, you might also want
* http://get.adobe.com/reader/
After the download,
#bring up the download manager ("Ctrl+J") and start your installs. As soon as the install comes up,
#close Firefox with File > Exit or "Firefox" button > Exit. Give Firefox some time to close and check that it finished via Windows 7 shortcut to WTM "Ctrl+Shift+Esc" in the "Processes" tab make sure that firefox.exe is no longer running -- if it is terminate it by selecting the use "End Process" button or from context menu.
#proceed with the install
'''Warning''': this is the Adobe site and they have chosen to to provide crapware along with their own product. Only install the product you were planning to install. Do not install additional products: including -- "Free! McAfee Security Scan Plus" or "Google Chrome". Installing Google Chrome on your own and installing it because it is offered on the Adobe site are two different things.

Some people will have a problem with Hardware acceleration, right-click in the flash area, click in settings..., then see if change setting makes a difference.

Problems installing adobe flash player to use with picnick editing on picasa

I want to edit a photo on Picasa.com. To do that, I must install Adobe Flash Player. The flash player has downloaded but does not appear to be installing though I receive a successful installation message. When Picnick did not open, I was directed to a help page but none of the tips made sense to me. Has anybody else with my operating system had and difficulties and then solved them???

Never mind. It seems to be working now. I think I just needed to unblock pop-ups.

How can i install adobe flash player on my i mac OSX lion

I just bought an I mac that runs on OSX 10.7.2 lion and cannot install Adobe flash player 10,0. I need it for looking to Youtube videos
Can anybody help me?
Charles

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 what version of Flash player you actually have installed: http://kb2.adobe.com/cps/155/tn_15507.html
You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS. Version 11.0.1.152 onwards is for Lion.
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/909/cpsid_90906.html
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.

After installing Adobe Flash Player latest update unable to watch iplayer due to "plug-in failure"

the Adobe Flash player update instruction showed on screen. I followed the simple install instructions. It stated everything had installed successfully, but when I tried to watch iplayer programme the message: plug-in failure appeared, and I was unable to watch any programmes and unable to even listen to radio programmes. This has never happened before. What should I do please? ;(

Adobe is working on a bug fix. This article documents the workaround (which is to use the earlier version for now):

Problem Installing Adobe Flash Player for Mac Air (Yosemite)

I got a message saying my Adobe Flash Player was out of date. This seemed strange because I'd been accessing videos within the last hour with no problems. I went ahead and opened the Mac version installer downloaded of the Adobe site. The install started and after inputting an Admin password, the download reached 25% almost immediately. Unfortunately, it's been stuck at 25% since then. I've tried starting over, deleting the download and re-downloading the update with no success. I've also temporarily disabled my AdBlock and AdBlock Plus. I tried to uninstall AFP so I could start over but the box that's supposed to tell me what uninstaller version to download has an error message saying I need to update AFP.
How can I fix this?
Edit: I thought maybe I was downloading an AFP for an earlier OS (I'm running 10.10.2). I made sure to download the latest version of AFP for Mac possible. The install is now stuck at 30%. (Just to be clear, I downloaded the install package with no problem - the issue is with the install program itself pausing at 30%.)
Edit 2: I figured out which uninstall package I needed (using this page: Uninstall Flash Player | Mac OS) but upon reinstalling AFP, it's stuck again at 25% of download.
Edit 3: The message "Connection failed. Trying to reconnect" has appeared, followed quickly by "connection failed". Guess I'll try again.

I've double-checked to make sure that I've selected "Allow Internet Plug-ins" under Safari>Preferences>Security. I've read in other threads that this is one possible solution but it isn't useful to me since I've uninstalled AFP and but I've been unable to reinstall it.
Edit: I'm not sure if Youtube is supported by a different software package but I can watch any videos on that site with no problem.

Problem Installing Adobe Flash Player on my Computer

Last week I installed Webroot Antivirus and Spy Sweeper on my computer and since then I cannot load my pictures on Facebook or send them to CVS or Walgreens to develop them. I have tried many times to load Adobe Flash Player, followed all instructions and nothing. I am totally frustrated. I waited over an hour on the phone for an Adobe technician and all he could do was direct me to this forum. I have a Dell computer, 32 system. I normally use Windows Explorer as my browser. Can somebody out there help me please?

This reply is to both of you trying to help me through my ordeal with Adobe Flash Player. I followed both of your advices to no avail. I even enlisted the help of my husband to see if I was doing something wrong or missing a step. He assured me I was doing everything by the book.
Well, bottom line is number
1: I never found "Extensions Adds ons and Plug Ins" in Firefox. I looked everywhere and it's simply not on my screen. I opened everything, looked at every line, every box, every space (with my husband next to me looking also).
Number 2: I got a message that reads: Firefox prevented this site (get Adobe.com) from asking you to install software on your computer.
By the way, I uninstalled Webroot at the beginning and never reinstalled it. Restarted my computer. Tried all the steps you guys suggested, restarted my computer I don't know how many times.
One time I got Adobe Flash Player installed "successfully" and then I got excited and tried YouTube, videos on Facebook, CNN and guess what? Nothing. No Adobe Flash Player.
By the way, my husband has the same problem at his work computer. He got an Information Systems technician to work on this and voila! he could not fix the problem either. Any other suggestions out there? If anybody from Adobe reading this?
To say I am fed up is putting it mildly. I am so mad at Adobe for putting this piece of garbage out there. I can only compare it to Vista.
Oh by the way, I keep getting this notice that my" windows drivers are out of date" and guess what? I have no idea which ones because they don't say. I checked my updates and supposedly I am up to date. I went to Microsoft and they have a million, so how am I supposed to know which ones?
I am also upset at Microsoft, ha, ha.
I am going to bed, tomorrow will be another day.

Installed Adobe Flash Plug-in Player many time,Safari5.1 not Recognizing Flash Player

I have asked and requested for help for my last Safari 5.1 Problem and I did get some help but the person didn't finish helping me or didn't answer my questions the second time around, I am hoping that I get a complete and full help and answers to my other Problems that I am still having with Safari 5.1 on my Snowleopard.
My Continuing Problem that I am having is; when I had updated my Snowleopard to Safari 5.1 I was having a Flashplayer Plug-in problem so I updated to the new current Adobe Flash Player, after doing the update, My safari 5.1 isn't recognizing the Flash Player Plug-in whenever I go to a web site that uses or has a embeded Flash Plug-in in it Safari doesn't reconize the installed Flash Player Plug-in and doesn't play the embeded Plug-in on the web site, I have installed the Flash Player several times I even installed the Shockwave Plug-in Player that too hasn't helped Safari 5.1 to recognize the Flash Player Plug-in.
After installing the Flash Player Plug-in Safari 5.1 How come Safari isn't Recognizing my Flash Player?
Does anyone have any suggestions that can help me solve this Problem and get Safar backi to start recognizing the Flash Player Plug-in again?
If anyone can help me and has a solution to my Problem and I have more questions will that person please get back to me? The other person didn't get back to me when I had more questions from my last Problem and my last problem still isn't solved.
Mrs. Trisha Foster

Tisha, I too get quite bent out of shape when not a single soul in this forum gives me the courtesy of a reply. It's especially bothersome to me since I know that many literally "live" in this forum only to answer questions and rake up thousands of "points" to show off. And yet, when a really tough question comes, no answers are to be found.
Although I don't have the solution you're looking for, I would like to chime in with my own Safari 5.1 experience in hopes it can help you better decide on what to do (which may be to downgrade to an earlier version of Safari or use Google Chrome instead).
You are using Safari 5.1 under Snow Leopard while I am using Safari 5.1 under Lion. You have a problem whereby the Flash plugin doesn't load at all, whereas the problem I have is that the Flash plugin loads but is basically unusable.
When using Safari 5.1 and the latest version Flash plugin under Lion, my web pages partly lock-up or freeze after I display Flash video content. Specifically, I cannot scroll up or down by using gestures on my Apple mouse. And after using gestures to scroll up or down if I then resize the browser window, suddenly the place that I scrolled to (and couldn't see originally) appears. I have to quit Safari 5.1 and relaunch it to get it working again. But if I encounter another Flash object, the same partial lockup occurs again. I am using Click-to-Flash to allow me to continue using Safari, but every now and then I forget that this problem will occur and I click to view a Flash video and it locks up again.
I have installed the latest version of Flash player, but to no avail. It's a very serious problem that did not happen in Safari 5.0 under OS X Snow Leopard.
Furthermore, if I switch to Google's CHROME or another browser under OS X Lion, I do not have this problem at all.
What this means is, even if you are able to get the Flash plugin to load in Safari 5.1, will your web pages lock up as they do in my case? In any case, I believe it shows that Mr. Job's hatred of Flash in general has led Safari engineers utterly ignore how the new Safari 5.1 plays with Flash. It's a travesty and an absolute crying shame. I say this as someone who is not necessarily a fan of Flash. But until Flash is completely dead on the web, Apple should support it on their desktop computers under any flavor of OS X. To avoid doing that is nothing more than a slap in the face to all owners of Mac desktop or notebook computers. And having owned a Mac since the 128k in 1984, I don't say these words lightheartedly either.

Problem installing Adobe Flash Player

The problem I am facing is that I cannot install the newer version of adobe flash player. My current Adobe Flash Player - Version is: 12.0.0.70 and I am working on Windows 7-64bit. After I download the install file from the official site (http://get.adobe.com/flashplayer/download/?installer=Flash_Player_12_for_Other_Browsers&os =Windows%207&browser_type=KHTML&browser_dist=Chrome&d=McAfee_Security_Scan_Plus_Chrome_Bro wser&dualoffer=false), I cannot install it any further. The install file will open and after pressing “run” and confirming installation (“yes”) it will show a caption “an error has occurred in the script on this page”. (The errors are not the same everytime.) Any help would be appreciated, thank you for your time.
