Flash Player is available from the Firefox Plug-in Finder Service. This means that if the Firefox browser does not

disabled, they should upgrade their Flash Players to version 9 before continuing. You can put this in the

These upgrade processes result in a different upgrade experience than the experience of the user who upgrades

by using Express Install. Express Install provides a clean installation and returns the user to the original page.

These alternative paths require more steps and in some cases do not provide users with a return path to the

original application.

You can do basic version detection without using Express Install. For an example of this, see the files in the

/templates/client-side-detection and /templates/client-side-detection-with-history directories.

Other techniques for upgrading Flash Player without Express Install are described in the Flash Player Detection

Kit. These include using server-side logic and writing a custom SWF file to perform version detection and instal-

lation. For more information, see the Detection Kit documentation at www.adobe.com/go/fp_detectionkit.

Note: Netscape users who do not initially have any version of Flash Plug-in installed may be redirected to a Netscape

download page rather than the Flash Player upgrade page. To avoid this, instruct your users to select Edit > Prefer

ences > Navigator > Helper Applications and deselect the Always Use the Netscape Plug-in Finder Service to Get Plug-

ins setting. If this setting is selected, Netscape ignores download location specified by the

wrapper.
