How do I fix almost all Shockwave issues?
An earlier version of Shockwave Player is pre-installed with most popular Internet browsers. Sometimes, damage to the Shockwave Player that's already installed can prevent your upgrading to the latest Shockwave Player. You can resolve almost all difficulties encountered with the Macromedia Shockwave and Flash Players by taking the following steps:

To fix most Shockwave issues:

1	Make sure you have the latest version of your Internet browser. Note: Navigator 6.0 is not compatible with the Macromedia Shockwave Player. Update to the latest version of Netscape for Shockwave Player support. Download the latest versions of Microsoft Internet Explorer, Netscape Navigator/Communicator, and America Online at their web sites: Microsoft Internet Explorer http://www.microsoft.com/windows/ie/ Netscape Navigator http://channels.netscape.com/ns/browsers/ America Online http://www.aol.com/ If there is a more recent version, download its installer to your desktop. Don't run this installer yet.
2	Uninstall Shockwave Player. You can download a Shockwave Player uninstaller for Windows and Macintosh OS: Shockwave Player uninstaller (Windows) Shockwave Player uninstaller (Macintosh) Save the uninstaller to your desktop, then quit/exit any applications you have open. Launch the uninstaller from your desktop and follow the instructions in the dialog boxes which appear.
3	Uninstall Flash Player. To uninstall Flash Player, you must delete the Flash Player plug-in or ActiveX control. The path to the Flash Player depends on the operating your computer uses: Windows 95/98 Delete the swflash.ocx file in the Macromed directory: C:\WINDOWS\SYSTEM\Macromed\flash\ Windows NT Delete the swflash.ocx file in the Macromed directory: C:\Windows\System32\Macromed\ Netscape for Windows Delete the NPSWF32.dll file in the Netscape plugins directory: C:\Program Files\Netscape\Communicator\Program\Plugins Macintosh Delete the Shockwave Flash NP-PPC file in the plug-ins folder of your Internet browser.
4	Restart your computer.
5	If you downloaded the installer for a more recent version of your Internet browser, launch that installer now and follow its instructions.
6	Finally, reinstall the Shockwave and Flash Players Note: If you are using Internet Explorer for Windows and no dialog boxes appear when attempting to download the Shockwave and Flash Players, you may be experiencing an issue with Microsoft's Install On Demand feature. If you had previously indicated to Internet Explorer that you did not wish to install the Macromedia web Players, Install On Demand will prevent their subsequent installation. You can undo this setting with the executables below: For Shockwave Player For all other players and uninstallers

 

I'm trying to download Shockwave Player, but I can't. How can I get Shockwave Player?
An earlier version of Shockwave Player is pre-installed with most popular Internet browsers. Sometimes, damage to the Shockwave Player that's already installed can prevent your upgrading to the latest Shockwave Player. This can usually be fixed by uninstalling, then reinstalling, Shockwave Player.

You can download an uninstaller for Macintosh and Windows:

Shockwave Player uninstaller (Macintosh)
Shockwave Player uninstaller (Windows)

After you've uninstalled Shockwave Player, reinstall it.

Note: In some cases, it's actually the browser which is preventing the successful installation of Shockwave Player. In such instances, simply reinstalling Shockwave Player may not work. Reinstalling or updating the browser, then installing Shockwave Player should take care of this.

How can permissions affect installing the Shockwave Player with Windows NT and Windows 2000?
If you don't have administrator access to your Windows NT, 2000, or XP-equipped computer, you may not be able to install the Shockwave and Flash Players successfully. Permissions can be tricky, but, in general, you should be able to install and use the Shockwave and Flash Players if your administrator gives you full access to the Macromedia directory (C:Winnt\System32\Macromedia\).

If this does not allow you to install and access the Shockwave and Flash Players, your administrator may need to experiment with varying levels of restriction to determine what works.
