Flash Player installation fails due to "The Flash Player ActiveX control could not be registered" error.

I am using Windows XP SP3 and Internet Explorer version 8.0.6001.18702

I have tried every applicable Flash Player download/install procedure provided on  http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html  My basic approach has been to:

  1. Verify I'm logged in as the administrator and that Internet Explorer security and JavaScript settings are correct
  2. Disable my Norton Real-Time Protection and close all programs that use the Flash Player
  3. Perform an uninstall of Flash Player with uninstall_flash_player.exe and delete all files in C:\Windows\system32\Macromed\Flash
  4. Cleanse the register using subinacl.exe (Windows Resource Kits) inconjunction with reset_fp11.bat file from Adobe
  5. Recycle computer power
  6. Attempt to install Flash Player using install_flash_player_11_active_x.exe

The above procedure has been repeated many, many times halting with "The Flash Player ActiveX control could not be registered" error.  Tried one time using msconfig to set a diagnostic startup to limit all the background software running. 

I have been to the Adobe forum for help and my above approach has incorporated all their inputs.  Please provide recommendations to support a successful install of the Flash Player.  Screen shots of error messages provided upon request.      - Jim


You are most likely infected with a virus or malware, I had this problem  awhile back and I just reinstalled my OS.

However, you can run some scans:

Download, install, update and do full scan with these free malware detection programs:


Malwarebytes (MBAM):   http://www.malwarebytes.org/products/malwarebytes_free

SUPERAntiSpyware: (SAS):  http://www.superantispyware.com/


Norton is not a very good antivirus, it sometimes does not work well with Windows, for now I would uninstall it:


Norton removal tool

then install MSE, you can uninstall it later if you choose and reinstall Norton.


MSE Download


MSE installation checklist

Then run scans with all three, this will be lengthy.

It will also ensure your system is healthy.

After scans, reboot, and then try your installation again.
