Update Flash Player on Windows Vista and Windows 7

Source

On some Windows Vista and Windows 7 systems, Flash Player is installed, but does not display Flash content.

If the installed Flash Player is between version 9.0.28.0 to 10.0.45.0, use a special installation utility that uninstalls Flash Player and then installs the latest Flash Player. This utility is for Flash Player for Internet Explorer. Follow these steps:

1. Open Windows Explorer and navigate to one of the following folders (only one exists depending on your operating system): 
   • C:\Windows\System32\Macromed\Flash\
   •  C:\Windows\SysWOW64\Macromed\Flash\
2. Locate the installation utility. It is a file with a name like FlashUtil10d.exe. The number and the letter, such as 10d in this example, depend on the installed Flash Player version.
3. Close all applications except for Windows Explorer.
4. Right-click the installation utility  (FlashUtil10d.exe in this example).
5. Select Run as administrator to execute the installer with administrator permissions.
   
   
    
6. Select Yes in the User Account Control display, if it pops up.
7. Select Install Now to install the update to Adobe Flash Player.
   
   
   
    
8. Check the license agreement and select Install in the Install Adobe Flash Player display. 
   
   
    
9. When the install completes, select Done.
   
10. Restart your computer.

Note: As of Flash Player 10.1, the utility in the Macromed\Flash folder only uninstalls the Flash Player, but does not start the automatic installation process as it did in Flash Player versions 9.0.28.0 to 10.0.45.0. If you use this utility for Flash Player 10.1, download the latest Flash Player and install manually. See Download Flash Player with the manual installer.
The Flash Player 10.1 uninstall utility in the Macromed\Flash folder has the following names:

• FlashUtil10*_ActiveX.exe
• FlashUtil10*_Plugin.exe

The * in the name is a letter that depends on the Flash Player 10.1 version. For example, FlashUtil10h_ActiveX.exe is the name for Flash Player 10.1.53.64.
Both of these utilities uninstall Flash Player for Internet Explorer and Flash Player for other browsers such as Firefox. If you want to uninstall Flash Player for Internet Explorer only, use the Windows Control Panel to remove the program Adobe Flash Player 10 ActiveX. To uninstall Flash Player only for other browsers, remove the program Adobe Flash Player 10 Plugin.
