Resolved Question

Flash Player 11 doesn't install.

Vista/IE9. Reloaded PC about 2 months ago. Haven't been able to play videos since. Have uninstalled Flash, rebooted, and reloaded from multiple sites - several at Adobe, Enet, and standalone reload from forum comments. Have reverted to IE8. Same results. Upgraded to IE9. Same results. Have run Norton registry cleaner and Ccleaner.

Try this test.

Go here;

You may have to wait for the page to load then Refresh the page. If you see the animation then Flash is installed correctly and works.

In that case, right click the animation, select Settings, make sure the first, (left hand) tab is chosen, then remove the tick for "Enable hardware acceleration". Retest on any online video site.

Does that work?

Let's try the Adobe Removal Tool

But before we do, can you get any videos to play from the hard disk or anything you have elsewhere?

I don't mean online in a browser, I mean video files you have yourself. If not, then this may well be a video driver problem.

You say you reloaded Vista a couple of months ago. Why was that necessary?

How did you do this reinstall, what was the process you used? Windows does need drivers and these are usually held on a separate CD.

Assuming you can play videos, try the Adobe Removal tool at

You may need to check whether you are running Vista 32 bit or 64 bit and tat page tells you how to do that.

Download the right file and save it to your hard disk. The Desktop is a good 'temporary' storage area. Close down all browsers and any other open applications and run that removal tool.

After it's done, reboot, (restart), the computer. This updates the registry and any System files.

Return to that Adobe web site and follow the links to test the uninstallation, then follow the link to reinstall Flash.

Good luck.

Tell us more

about this computer, age, make and model and hardware, eg what hard drive is installed, SATA, SSD?

Check if DMA Mode is available and enabled on the hard drive. Look at the link below for guidance how to do that;

Even if DMA mode is enabled, try the 'switch' method. Disable DMA mode, click OK then return immediately to re-enable DMA mode. A reboot might be required after re-enabling to see if it has worked.

If a reinstall back to factory settings hasn't worked properly then may be there are hardware issues.

I forgot.

I asked if videos play ayway, eg videos held on the hard drive. If not, what happens?


- Collapse -
Playing videos

Can play any file that Windows Media Player recognizes. Any file needing Flash won't play.

Tried Using The Manual Flash Installer Like This?

First, if you haven't already, visit the link below, then download the Flash uninstaller tool. After downloading, then uninstall Flash using the tool.

Once that's done, then click on the links below to download the standalone installers for Flash. If you use more than one type of browser, you need to download BOTH installation files and run them.

Please note: Clicking on the links below will immediately open the download dialogue window.

For Internet Explorer:

For Firefox and other non-IE browsers:

Hope this helps.

Just A Thought Or Two...

Have you also installed the latest Java? If not, please do.. Some of those Flash videos also require Java applets to function.

Disabled the Windows firewall yet? If not, please disable it from the Control Panel.. The Norton product should have it's own firewall.

We've also seen a few issues like yours with Norton products .. Just for giggles, try uninstalling Norton and see if it allows the videos to run correctly. Simply disabling won't help.. It will need to be uninstalled. You can reinstall it afterwards if it doesn't help.

Hope this helps.

no such luke

I thought I had it for a moment. Did all of the above to no avail. Then unistalled Norton and tried again. Nada. Then tried to reinstall Norton and it failed. Said I needed to run their "deep cleaner". I did and then the reload on Norton when smoothly. But upon reinstalling Flash again, I still can't reload Flash.

If Norton Won't Reinstall Either... That's A Clue...

It's sounding more like you have a malware problem.. If you haven't already, please follow the steps below and see what you find:

If you can download the tools listed below on the problem computer, great, but you may need to use a separate, clean computer, download the tools, copy them to a DIFFERENT flash drive or CD, then transfer them to the infected computer.

Once that's done, then restart the computer into "Safe Mode with Networking" and use the instructions below. If you can't start in Safe Mode, then run all the tools while in "normal" Windows first, then run them in Safe Mode afterward.:

After downloading or transferring it to the problem machine, run the
following tool to help allow the removal programs below to run.
(courtesy of Grinler at are 3 different
versions. If one of them won't run then try to run the other one. Be
patient.... as a black window should open, then close after finding all
the background programs.Vista and Win7 users need to right click and choose Run as AdminYou only need to get one of them to run, not all of them.



IMMEDIATELY after running the "Rkill" tool above, run/install the Malwarebytes and
SuperAntispyware installer and update files from the links below which
you've also copied to a CD or flash drive, and transfered to the problem
machine. Do NOT restart the computer after running Rkill.Once
downloaded and before transferring Malwarebytes and SuperAntispyware to
the problem machine, rename the program installer "mbam-setup.exe" file
to something else like "Gogetum.exe", then copy the installer file and
the update file to a CD or flash drive.. Transfer the file to the
problem machine, then install the "Gogetum.exe" file, then run the
update to get the program current.. After that, run a full system scan
and delete anything it finds.

Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)

Malwarebytes Manual Updater link

Next, install and run a full system scan with the SuperAntispyware program
and the manual updater from the links below. As before, you may need to
rename the installer file to get the program to install.:


Manual Update

And after that, if everything's fine by you can't connect to the internet,
then follow the procedures below to check your network "proxy" settings
again.Open Internet Explorer and go to Tools-Internet
Options-Connection Tab. Click on the LAN settings button. IF there is a
check mark next to "Use a proxy server for your LAN", uncheck it. Click
OK. Then OK, again.

Hope this helps.

Super Antispyware

thanks for the continued interest. Got the same results. Super Antispyware did find one spyware and about 30 cookies. I ran Norton again and it found an additional dozen cookies. If my son-in-law can't help, I think I will go through the reload of Windows again. I've done this multiple times (on different PCs) an never had any problems. I'll keep you posted of the solution.
Thanks again.

(NT) And You Ran Rkill & Malwarebytes Also?

Rkill and Malwarebytes

Yes. I have a 3rd notebook that I reloaded the system onto the same time as I did the one I'm having a problem with. But have put nothing else on that PC except Norton. I used it to download Rkill and Malwarebytes on a thumb drive. I then ran those two programs from the thumb drive in the problem PC in the protected mode. After rebooting, I went to Cnet and reinstalled Flash. Flash again said it was installed and running. I then went to Youtube and tried to play a Flash video. Got the same alert that I needed to load Flash.

A Question That Should Have Been Asked Earlier

Is this a 64 bit computer? If so, which version of Internet Explorer are you using? Both versions of IE require a separate installation of Flash.. If you're opening the 64 bit version of Internet Explorer, then you need to install the 64 bit version of Flash.. And in most cases, it's better to use the 32 bit version of IE to run Flash videos from anyway..

Hope thi shelps.

Another answer to this problem

Flash is flatout not supported in Vista 64 bit, and several other OS. ... "can't install flash 11 vista" for several ways to fix this.
