Adobe Flash Player 10.1.102.64 download error: can't retrieve essential parameter (1629.301.749).

Getting error message can't retrieve essential parameter (1629.301.749), after Adobe Download Manager pop up for installation. I have uninstalled/reinstalled flash player numerous times. http://www.adobe.com/software/flash/about/ notes I have the latest version installed, but I am unable to access full Adobe Flash Player functions on various sites such as Facebook, etc. I can't find anything in the Adobe KB. Any help is greatly appreciated!

I'm back. The dwld worked for 2 days and now I'm back to the notification that I need to update my Flash Player. I used the link you previously provided http://www.adobe.com/products/flashplayer/fp_distribution3.html to download the .exe again, but I'm getting the same message for both Mozilla & IE. As I previously stated, there is no file folder in the Registry for Flash Player under HK HKEY_LOCAL_MACHINE/Software/Adobe. Does anyone know the KEYS for Flash Player, that I could add manually?
System Information:
Win XP Home, SP 2
IE 8.0.6001.18702
Mozilla 3.6.12
Flash Player 10.1.102.64
Thanks!

Can't install newest reader. Error: "Can't retrieve essential parameter"

I get this error: Can't retrieve essential parameter (12250.305.770).
Then the installation just hangs at 66% completion and nothing more happens. Win XP, latest patches, IE 7.
TIA!

If possible, temporarily disable your AntiVirus/Windows Smartscreen and run it. You can also boot into Safe mode with networking, download and run it.
Virus scan of the file showing it's clean. Flagged by Symantec/Norton as being non popular. Though not on this list Windows 8+ Smartscreen will also tend to block the download if Smartscreen is enabled (system-wide)

The main reasons why any exes I make are flagged.
1. Not popular so it has no reputation online of being good/bad so bad is assumed. Kind of like a person on Ebay with zero feedback.
2. Doesn't have an embedded SSL cert pointing back to my site.

Adobe Flash "Can't retreive essential parameter 16291.301.749"

Receiving the error message from Adobe Flash active-x install in IE 8 32-bit on Windows XP 32-bit on several systems at work that were just rebuilt (No previous version of Adobe Flash). All Microsoft patches were installed. All three systems install DLM, DLM starts running, and then I receive the message. I would like more information on this error since this is a work situation and I have multiple systems experiencing the error. Also I have these questions:
Will installing Adobe Flash from the actual exe or msi program disable the Flash update notifications through DLM?
What is the exact cause of the above error message? In other words, what is the "missing essential parameter 16291.301.749"?
Please respond quickly as I cannot deploy these systems until they are patched properly.

Do not use the DLM, especially when deploying Flash Player; download the installers (without DLM) from http://www.adobe.com/products/flashplayer/fp_distribution3.html

After I downloaded the new version of Adobe Flash Player 11.3.300.262, I can't seem to play games with my friends on Yahoo Messenger.

It could be a coincidence but when I upgraded to the latest version of Adobe Flash Player 11.3.300.262 I can't seem to play any games on Yahoo Messenger with my friends. I know when I updated for some reason I had to try 3 times before it took it. It shows it's updated. I'm wondering if I have to un-install and re-install it. Also, I never use Internet Explorer 8 but when I went in there to check I found a plug in check link there and it showed over there that Adobe Flash Player needed updating but it was an older version and not the one Foxfire had me update too. Now I'm really confused if this is causing a problem. I have never had to check Internet Explorer for plug ins before. Have always just updated in Foxfire since that's what I use. The Adobe Flash Player seems to play videos okay so not really sure if that's the issue or not. My Java plug-ins have been fine and have been updated awhile ago, so I know it's not that. Any help is appreciated. Thanks!

Well, after hours of trying to figure it out I gave up and un-installed and re-installed that last verion of Adobe Flash Player and now it seems I can play games again in Messenger. Everything else had been fine just that. I can only figure it was because it was having a hard time updating the first time and took me 3 tries. So even though it said it was installed, apparently it wasn't done correctly.
Though when I couldn't figure out what was wrong at first I looked and checked to see all the things were enabled that were supposed to be and they were.
I even tried to go to the Adobe site and download the last version I had and couldn't find it. Kept coming up with the new version. Others said if you download a particular older version it may not have all the security features in it.
This really gets to be a bit much, especially when you're by yourself and have only a smattering of knowledge of technical things.
Thanks fore responding to my question.

HT1338 still asking for adobe flash player even when I downloaded it already

I downloaded adobe flash player as directed but still cannot open my teacher's email link, still asking for my adobe flash player.

You have to download AND install Flash Player. Did you run the downloaded Flash Player installer?

Keeps telling me to download adobe flash player and its already downloaded

i am new to the MacBook Air. I downloaded a game from the apps store. Whenever I try to play, it keeps telling me to download the Adobe Flash Player and its already downloaded and is up to date.

No game from the App Store could be prompting you install Flash. Only a web page could do that. Does the game open a web page?

I Need Help for the popup message every time I go to safari: "Warning! Old version of Adobe Flash Player detected. Please download new version."???

I Need Help for the popup message every time I go to safari: "Warning! Old version of Adobe Flash Player detected. Please download new version."???

If you are talking about Safari on the iPad, there is no version of Adobe Flash for iOS and there never has been. Clear Safari, close the app and reset the iPad.
Go to Settings>Safari>Clear History and Website Data
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
If you are talking about Safari on your Mac, you are in the wrong forum. But I would still clear the cache, quit Safari and restart the Mac.

I fould a hack that makes the sites think you have the latest (Intel) version of Flash installed. So I installed it & it works with Firefox, TenFourFox & Safari. Here's the info.
Download this http://www.steelbin.com/FPforFBPPC.zip to your desktop, unzip it, and replace the current Flash Player plug-in which is in your main/Library/Internet Plug-Ins folder, (not the user Library). Save the old one just in case this one doesn't work.

Adobe Flash Player Installer gets stuck "downloading" and won't proceed

I'm on Mac OSX 10.10.1, using Safari and Chrome as browsers. I recently upgraded to Yosemite and since then have gotten error messages that I don't have Flash installed. When I download the Installer, it gets stuck and won't move past "30%" downloaded. I've left it for hours, and it is still at 30 when I return. Is there a permissions issue that I could play with to allow it to continue installing? Any suggestions for what to try to get this installed?
I've been able to download the installer itself, but the problem comes after I double-click "Install Adobe Flash Player." See screenshot below.
This is where it gets stuck:

Use the offline installer http://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player_osx.dmg

What was the latest version of Adobe Flash Player for PowerPC. And where can I download it.

It`s all said in the headline. Hoping for an answer.
Thank You

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,10.3.183.23 or later, is for Intel Macs only running Tiger or Leopard, as Adobe no longer support the PPC platform. Version 11.4.402.265 or later is for Snow Leopard onwards.
* Unhelpfully, if you want the last version for PPC (G4 or G5) Macs, you need to go here: http://kb2.adobe.com/cps/142/tn_14266.html and scroll down to 'Archived Versions/Older Archives'. Flash Player 10.1.102.64 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/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.
(If you are running a PPC Mac with Flash Player 10.1.102.64 and are having problems with watching videos on FaceBook or other sites, try the following solution which fools the site into thinking that you are running the version 11.5.502.55:)
Download this http://scriptogr.am/nordkril/post/adobe-flash-11.5-for-powerpc to your desktop, unzip it, and replace the current Flash Player plug-in which is in your main/Library/Internet Plug-Ins folder, (not the user Library). Save the old one just in case this one doesn't work.

Have installed adobe flash player and is in downloads, and my documents, but I can't open it due to conflicting instance. No idea what to do next

Trying to open adobe flash player so my daughter can play educational games. Think it's downloaded ok, but it won't open due to 'conflicting instances'. I don't even know what that means!

This is the full procedure for installing Adobe Flash for Firefox.
1.Download the Flash setup file from here: 
[http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe Adobe Flash - Plugin version]. 
Save it to your Desktop. 
2. Close Firefox using File > Exit 
then check the Task Manager > Processes tab to make sure '''firefox.exe''' is closed, 
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
* On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen).

Adobe Flash Player Installer always stops downloading

I just formated my Macbook and made a clean reinstallation of OS X (10.10.1). However, apparantly I can't install the adobe flash player (for safari). I download it from http://get.adobe.com/de/flashplayer/ but the installer always pends on downloading without making any progression. I don't have my firewall active. I already tried restarting my computer several times.
On the help page for installation issues this problem is listed. It is suggested to download a direct installation from http://fpdownload.macromedia.com/pub/flashplayer/current/support/install_flash_player.exe but this link is not available.
Every help is much appreciated.

Hi Maria
I just noticed the link i posted earlier is for windows as well as the help page from where I found it: http://helpx.adobe.com/de/flash-player/kb/installation-problems-flash-player-windows.html
However, the help page for OS X does only provide a link for a direct installer, which is not available as well: http://fpdownload.macromedia.com/pub/flashplayer/current/support/install_flash_player_osx. dmg
After all I found that the flash player should be integrated into the OS since 2013 and that apparantly my recovery volume for the installation of the OS X has been defective. I formated my Macbook again and installed the OS from another volume and 'voilà' flash player is now integrated and I do not even need to install it manually.
Anyway, thank you very much and have a good day.
