If you install Adobe Flash Player version 10 on IE 8 64-bit editions, you may not be able to view ActiveX content in your 64-bit browser and start experiencing ActiveX warnings when trying to run Windows native management tools. Windows Services console fails to load with error messages such as:

  1. Your current security settings prohibit running ActiveX controls on this page
  2. You have blocked a Publisher of one of the controls, as a result the page may not display correctly

Some users reported same errors with other management tools as well. Adobe states that Flash Player 10 does not run in most 64-bit browsers and it fails to install in a 64-bit browser, however, I tried an installation and it completed successfully, while I still experienced the above mentioned problems afterwards. On other occasions, installing the Flash Player on a clean 64-bit IE 8 did not create the problem mentioned above; hence, the problem may be specific to certain environments or triggered by a third-party component when you install the Flash Player!


According to Adobe, you must use a 32-bit Web browser on your 64-bit operating system to install the Flash Player. All major browsers are available in 32-bit versions and the Internet Explorer 32-bit browser is the default browser on Windows 64-bit systems.

According to Microsoft, knowledge base KB907343 should help you in solving the problem. Additionally, one would need to delete a registry zone entry located just before zone 0 as referred to in the mentioned kb. This problematic key would normally be labeled with a character or number, where in my case it was named L.

This last part actually solved my problem but I would like to remind you to be cautious with registry modifications and I suggest to back up the registry before performing any actions on it!
