Depend on your OS. If is Windows IE, some issues has found on this.
Try this :
our version of Windows is either a 32-bit operating system
or a 64-bit operating system
. A 64-bit operating system can run both 32-bit applications
and 64-bit applications
.Your browser, such as Internet Explorer, is either a 32-bit application or a 64-bit application.
Flash Player works only with a browser that is a 32-bit application.
On a 32-bit operating system, your browser is always a 32-bit
application. However, on a 64-bit operating system, your browser is
either a 32-bit application or a 64-bit application. Make sure you are
using a 32-bit browser by following these instructions:
Windows with Internet Explorer
To make sure you are using a 32-bit version of Internet Explorer, follow these steps:
Windows with other browsers, such as Firefox, Google Chrome, or Opera
Internet Explorer's Help menu, select Help > About Internet
Explorer. (In some versions of Internet Explorer, select the question
mark in the upper right corner to select About Internet Explorer).
- If you do not see the words "64-bit Edition" next to the version
number, you are running a 32-bit version of Internet Explorer. Continue
to Determine the Flash Player version you installed, if any.
- If you do see the words "64-bit Edition", go to Flash Player on 64-bit operating systems (TechNote 6b3af6c9) to continue troubleshooting your Flash Player installation.
No official 64-bit version of these browsers is currently available on
64-bit Windows operating systems. Therefore, unless you are using a
test version of a browser (not typical), your browser is a 32-bit
application, and therefore, works with Flash Player. Continue to Determine the Flash Player version you installed, if any
2. Determine the Flash Player version you installed, if any
Before you troubleshoot Flash Player installation, determine the
version of Flash Player you have installed, if any. You can see if it is
working and whether it is the latest version available for your
operating system. Follow these steps:
- Go to http://www.adobe.com/software/flash/about. If
you have already successfully installed Flash Player, the page displays
the Adobe Flash Player version as shown in the following image:
Note: The version number in this example might be different than the version you have installed.
If you have not successfully installed Flash Player, you will not see the image.
- The same page http://www.adobe.com/software/flash/about has
a table that shows the latest Flash Player version available for your
operating system (for example, Windows or Macintosh) and your browser
(for example, Internet Explorer or Firefox). If the version information
shown in step 1 does not match the latest version shown in the table,
upgrade to the latest version. To upgrade, continue to Uninstall previous versions of Flash Player.
:Internet Explorer uses a different Flash
Player than other browsers such as Firefox or Google Chrome. Therefore,
if you sometimes use Internet Explorer and sometimes use another
browser, you might have installed a different version of Flash Player
for Internet Explorer than for other browsers.
3. Uninstall previous versions of Flash Player
Before you install Flash Player for any Windows browser, uninstall
all previous Flash Player versions and restart your computer. Follow
- Uninstall all previous Flash Player versions and restart your computer. For Flash Player uninstall instructions, see Uninstall Flash Player (TechNote tn_14157).
- Restart your computer after uninstalling.
- If you are using Internet Explorer, continue to Verify Internet Explorer security and ActiveX settings. Otherwise, continue to Download and install Adobe Flash Player.
4. Verify Internet Explorer security and ActiveX settings (skip for other browsers)
Make sure that Internet Explorer security default level is set to
Medium. This level allows viewing ActiveX controls, such as Flash
Player. To set browser security to Medium, perform the following steps:
- Open Internet Explorer.
- Choose Tools > Internet Options.
- Select the Security tab.
- Select Trusted Sites zone.
- Select the Default Level button. (If the Default Level button is dimmed, continue to the next step).
- Move the slider until the security level is Medium.
- Select Apply.
- Select the Internet zone.
- Repeat steps 5 - 7. When done, select OK.
