Cannot install Flash Player-Installer freezes

Running OS 10.10.2
Was unable to update, so followed instructions and uninstalled entire Flash app. Have downloaded update 3 times. Installer freezes during download/install process at 25% and does not continue.
Now I have no Flash and am unable to install.
Forum shows several other users with same problem; none of their posts have been answered.

joseywales41's solution worked for me (Please try the offline installer posted at the bottom of the Installation problems | Flash Player | Mac page in the 'Still having problems' section.)
Everything is back to normal now. Thanks!

I cannot install flash player on my MAC - (osx 10.8.4) - it downloads 50%, then clicks to "finish"

I cannot install flash player on my Mac - running OSX 10.8.4 and Safari 6.0.5. The progress bar show is as downloading to 50%, then converts to "installing" and immediately goes to 100% and says it's installed. But it's not. I get another Adobe Flash installer icon on my desktop instead. Help!

Hello,
Welcome to Adobe Forums.
First, remove Adobe Flash Player completely using Flash Player uninstaller for MAC : http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html
Download offline installer for Adobe Flash Player (MAC) from here : http://fpdownload.macromedia.com/get/flashplayer/current/licensing/mac/install_flash_playe r_11_osx.dmg
Once the file is downloaded, run the installer
Thanks,

I cannot install Flash Player because I am told 'sliprt.dll is missing'. How do I install sliprt.dll

I cannot install Flash Player because, I am told, 'sliprt.dll is missing'. How do I install 'sliprt.dll', please?

Cannot install Flash Player for Firefox

I am running Windows XP HE with SP4. IE and the latest version of Firefox are installed.
In both IE and Firefox, on attempting to install Flash Player with the standard link, I get an error message in a small window opens, title "getPlus+(R): Error," text "Unable to load a GUI," "OK" box. I got around this by locating a standalone installation for IE, which downloaded an installation file to my computer. However, this does not work in Firefox, even when obtaining access to that link from Firefox. The file executes, but Flash Player still shows as not installed in Firefox.
I cannot find any separate standalone installer for Flash Player for Firefox.
This error message appears to be generated by the Adobe Installer, a getPlus product. My thought was to uninstall the Adobe Installer, and try to start over. However, the Adobe Installer shows up in the list of installed programs reached through Control Panel, BUT clicking the button to uninstall the program does nothing. The program remains listed. I cannot find a location for the Adobe Installer program on my disk drive.

As I said in my first message, Adobe DLM appears in the "Add/Remove Programs" dialogue box, but clicking the Remove button doesn't do anything. The screen flickers for a couple of seconds, and Adobe DLM remains listed as an installed program. There is no installed program listed under the description getPlus or NOS.
I found useful information at http://www.findmysoft.com/news/Patch-to-Fix-Critical-Adobe-Download-Manager-Vulnerability- Released/ . Not to put too fine a point on it, information at various locations shows that the DLM has been a troublesome program.
IE did not list Adobe DLM, getPlus, or NOS as an addon. Firefox listed "getPlusPlus for Adobe 16263" as a plugin. There was not other extension or plugin listed under Adobe DLM, getPlus, or NOS.
Based on the information at the link cited above, I tried the following. First, in Firefox, I disabled the getPlusPlus for Adobe 16263 plugin. Removing it was not an option. First, using services.msc, I disabled the getPlus Helper service. Removing it was not an option. Third, I deleted the directory c:\Program Files\NOS and its subtree. I did not find anything relevant in the Application Data directories.
I then went to the link on the Adobe Web site to install Flash Player. (I know, it's already installed, but I wanted to see if the DLM would now function.) This time, the first thing that happened upon clicking the link to install it was that the site completed a new installation of DLM. However, on proceeding to the installation of Flash Player itself, I got the same error message noted above, "A GUI could not be loaded." So nothing changed. Opening services.msc again, I noted that the getPlus Helper service had been reinstalled, and was no longer disabled. The c:\Program Files\NOS directory had been recreated. I tried manually starting the getPlus Helper service, and trying the installation again through the Adobe Web site. Same result, no help. And note that DLM is not being cleaned up automatically as part of this process, as is supposed to happen.
I'm thinking that a previous installation of DLM left behind some corrupted relic that is preventing it from running properly. Very likely an incorrect registry entry. But good luck finding that one without help.
NOS Micro has a link to "Contact Our Support Team" at http://www.nosltd.com/index.php/support . Maybe as a last resort see if they would respond? Note that I can't locate a way to get support from Adobe except by paying $39.95 per incident for telephone support.
Thanks!

Cannot get Flash Player Installer to work.

I have tried many times over to install Flash Player but when the Installer pops up, it never begins the install process. It just sits there. One thing I was able to do was create a new admin user account and tried installing it on that account and it worked just fine. But I cannot get it to install on my main account. I'm using Windows 7 Pro. Have tried shutting down AVG and Firewall when running installer and nothing seems to help. Suggestions?

Adobe Flash Player download, install and allow it.
    Allow Plug-ins
    Safari > Preferences > Security
    Internet Plug-ins > "Allow plug-ins"
    Enable it.
    Press " Manage Website Settings" button for more options.

Cannot install Flash Player plug-in on Windows Vista through Mozilla Firefox

I own a Windows Vista basic version laptop and am currently browsing with Mozilla Firefox. Everytime I try to install the missing plug-in for Adobe Flash Player (the lego image) on the Flash Player homepage it pops up as Flash Player 10.0.45.2 and I agree to the terms of use and click "Install" but then I am asked what I want to open the file with and I don't know what file it is associated with on my computer (My computer often has this problem with .exe files though) . If I close the "Open With" box the installation says failed and gives me an option to "manual install, but when I go to the Adobe Flash Player site (with all other browser windows closed of course), and click "agree and download" a small box with a loading green bar pops up titled "Installing Adobe Download Manager" and stays there for about 2 minutes but nothing ever happens when I am redirected to the "Thank You" page afterwards, no dialog box w/ run or save ever pops up. I have added "get.adobe.com" to my allowed installation add-ons and pop-ups are also allowed on this page but nothing happens. I appreciate any input for my problem...Thanks

Hi, thanks for the update of info. In that case I would download this Flash Player Installer for Internet Explorer to your
Desktop:
http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_ax.exe When this window opens, SAVE it to your Desktop.
Before Running, Close all browsers, disable any applications that use Flash(check system tray-area of clock), make sure
in Internet Explorer>Internet Options that Security is set to Medium for the Internet Zone.
Now your Anti=Virus/Firewall can block the Install of the Flash Player ActiveX Control that must be installed. You may want to Disable those also. Windows Firewall is ok, no need to Disable it.
After Installing, make sure to Reboot(restart) your computer. Then go to this test site:
http://kb2.adobe.com/cps/155/tn_15507.html
Then using IE, go to Tools>Manage Add ons and check All add ons for Shockwave Flash Object...ActiveX Control..Flash10e.ocx(version 10.0.45.2) and make sure it is listed and Enabled.
If you have any questions or comments prior to beginning, just post back.
Thanks,

Cannot install Flash Player in Windows 8.1

Tried to install Flash Player in Windows 8.1 (32 bit). Used all the instructions; i.e, disable saftey, enable scripting, etc. An install box says Update KB2934802 is already installed. Searched computer for KB.....02 and Flash Player. Says none exist. Any suggestions?

Ever since Windows 8, Flash Player for Internet Explorer is written by Adobe ONLY. It's embedded by Microsoft, and you cannot:
- Update it
- Download it
- Install it
- Reinstall it
from here. You MUST update Flash Player ActiveX (for Internet Explorer) through Windows update. But... Using Windows 8.1 means you were forced to update to IE11, which has it's own problems and they can be summed up in three words...
"User-Agent Strings"
That doesn't mean a lot, I'm sure, but it's the root of your problems, and Flash Player has nothing to do with it.
Microsoft "rewrote" the User-Agent Strings for the abomination they call their latest and greatest browser. User-Agent Strings are what websites use to identify the browser you're using and provide the proper content for it's browser engine, like ActiveX stuff, and Flash or HTML5 video. Thanks to the geniuses in Redmond, WA, the User-Agent Strings for IE11 (which has a Trident engine), ID it as either "Gecko" (Firefox) or "Webkit" (Chrome). Problem is: when the site the directs to the content for one of these two engines, the Trident engine in IE can't intepret it and the site then sees IE as an "unidentified" browser.
The problem with an unidentified browser is that the plug-ins in that browser aren't recognized either, so even though you're up to date, it says you need the latest Flash Player when you use IE11. YouTube... has converted to HTML5 video so if it doesn't detect Flash Player, it can display HTML5 (MP4) video which requires no plug-in to play. Facebook can't do that, because HTML5 doesn't apply to games... only video.
Microsoft has no plans to "fix" the mess thay've created because they think it's a great idea to block you out of the websites you visit.
They recommend using "Compatibility View" and pretending that you're using an older verison of IE... Problem with that is that it's seen limited success, and you have to enable it for EVERY page that has problems... individually.
The REAL solution, like the original problem can also be summed up in three words:
"Use another browser"
Firefox (from Mozilla)
Opera (from Opera)
Safari (from Apple)
Chrome (from Google)
ANY of those will work where IE11 won't, with the Flash Player Plug-in (For all other browsers), and Chrome doesn't even need that because it has its own Flash Player plugin built in.

Cannot install flash player partially uninstalled

Dear community members,
I successfully installed Flash Player back in April. It was working well until a couple of weeks ago, when video clips wouldn't work sometimes, but did with a bit of coaxing. The sites affected were - Facebook, Iview (TV), Youtube,and my bank's website. The same applied when playing games. The situation has now degraded to the extent that I cannot access any of the sites listed, and get video/voice.
I downloaded the instructions to uninstall, and downloaded the .exe file and ran it (no problems). However, the instructions said to delete files in the system32\Macromed\flash directory, but when I tried to I was told I didn't have the right privileges. I have administrator rights. How higher can one Go?
I tried to install again, only to be told that Flash Player is already installed. How do I fix Flash Player, when I cannot uninstall or install it? Any suggestions would be gratefully received.
Regards,
Gazza

You have Shockwave Flash 10.1 r82 installed already.

Cannot install Flash Player without a password and I don't have one.

I cannot seem to install Flash Player without a password and I do not have one. What to do?

The password that's being requested (required) is your user account password ON YOUR SYSTEM (not for Adobe). You CANNOT install without an administrator account, and you CANNOT set up an administrator account without a password.

How do I prevent Adobe Website attempt to install Flash Player which freezes Windows e-mail browser.

For past several days, my Windows e-mail browser frequently freezes and must be closed. This occurs whenever message near top of browser states that Adobe website wants to install Adobe Flashplayer. Windows explanation states that termination is a result of Data Execution Prevention (DEP). How do I stop Adobe Website attempts to install Flash Player, or if that is not possible, what is a solution? I have uninstalled Flash Player in an attempt to resolve problem without success.

You can find a link and instructions for the last version of Flash Player compatible with PowerPC in this FAQ:
What version of Flash Player should I use with my Power PC based Mac?
For what it's worth, Apple itself discontinued support for PowerPC with their operating systems back in 2009 with the release of Snow Leopard. Regardless, I know its frustrating when your system is no longer supported. Hopefully the instructions I posted in the FAQ allow you to get Flash content running again.

Adobe Flash Player Installer Freeze up.

My problem might be a little different then some of the others. I have Windows 7/64 bit. I also have Adobe Reader, Acrobat and PSE9 installed. I have successfully updated flash player many times with the usual adobe pop up window. Presently I have ver 10.3.183.5. Yesterday I got the usual pop up window indicating a newer version (10.3.183.10 I assume). When I clicked "Install Now" it latched up with the following window:
After waiting, I clicked the "X" and received no error. My current version 10.3.183.5 is still working fine but no update occurred. The only install log entry with a current date is:
=O====== M/10.3.183.5 2011-09-28+15-05-16.627 ========
0000 [I] 00000010 "C:\Windows\SysWOW64\Macromed\Flash\FlashUtil10v_ActiveX.exe" -update activex
=X====== M/10.3.183.5 2011-09-28+15-15-58.760 ========
I'm not sure what the best way to proceed is. If you have a link to an downloadable installer, I can do that but if so, here are some questions:
1) Should I just run the installer or should I 1st uninstall 10.3.183.5 via "uninstall programs" ??
2) Should I turn off my virus (MSE) first?
3) Should I turn off the windows firewall first?
4) Should I run the installer from a clean boot??
Help will be appreciated.

I'd recommend trying the following steps:
1. Download the stand alone uninstaller
2. Close all your browser windows
3. Run the uninstaller
4. Restart your computer
5. Delete the following folder, depending on your operating system type:
Windows 32bit - c:\Windows\system32\macromed
Windows 64bit - c:\windows\syswow64\macromed
6. Download and install Flash Player located here:
Flash Player for Internet Explorer
Flash Player for other browsers

I cannot install flash player updates

I get the prompt that asks me to update flash. I give it the ok and when it goes to install the updates, I get a script error. It's been going on since last week. I've gone directly to adobe's website to try and dowload that way without success.

adobes website says"You have version 11.6.602.171 installed"
flash player says "active x version 11.602.180, plugin version not installed"

Cannot install Flash Player - says I need to download missing plugin

Firefox 3.6.10
Windows XP, SP 3, 32 bit
I always have to uninstall my current flash player before installing a new version. So I uninstalled, but when I try to install the new version, I get a message at the top that I need to install a missing plugin. All I get when I go there is GP.XPI downloaded which does nothing at all. What do I need to do? Thanks for any help!!

GP (GetPlus) is the Adobe download manager. Download the Flash Player installer directly from http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe (for Firefox) and you will not need any DLM.
