at this link...
applications must be closed before you run the Flash Player uninstaller. Quit all
running applications, including all Internet Explorer or other browser windows, and all Instant Messenger clients. Check the Windows system tray carefully to make certain no applications which might possibly use Flash Player are still in memory.

2. Download Adobe Flash Player
Flash Player is available for download from the Adobe Flash Player Download Center
3. Troubleshoot Adobe Flash Player for Internet Explorer
Before installing Flash Player, please check the following browser settings:
Internet Explorer ActiveX settings
Browser security settings should be chosen by you or by your system administrator. For single users who do not have an administrator, the Medium: Default Level allows you to view Flash content. For any Custom Level, ensure that both the "Download Signed ActiveX controls" and "Run ActiveX controls and plug-ins" options are set to "Prompt".
To change your security level:
- Open Internet Explorer.
- Choose Tools > Internet Options.
- Select the Security tab.
- Select Custom Level.
- Find the section "ActiveX controls and plug-ins".
- Set ' Download Signed ActiveX Controls' to Prompt.
- Set 'Run ActiveX Controls And Plug-ins' to Prompt.
If you are having trouble installing, make sure that your Internet Explorer security level is not set to High or to a custom level that does not allow viewing of ActiveX controls.
Windows Vista installation failure
On some Windows Vista systems Flash Player may be installed, but will not display Flash content. In some cases updating to the latest Flash Player using the included utility can correct the User Account Control settings that cause this problem.
To run the utility, find your installed Flash folder:
Computer user permissions
- Right-click C:\Windows\System32\Macromed\Flash\FlashUtil9d.exe
The letter changes with each Flash version, so may be "FlashUtilb.exe" or "FlashUtile.exe"
- Select "Run as Administrator"
- Follow the steps to complete the Flash Player installation
- Restart your computer
User permissions determine whether or not you are allowed to install ActiveX controls or plug-ins. If you don't have Administrator access to Windows NT, 2000, XP, or Vista you may not be able to install Flash Player successfully. Administrative privileges are required for the Windows system registry and for the C:\WINDOWS\system32\Macromed\Flash folder.
