I need to download flash player to download a catalog on line but do not need the additional software. How can I opt out of the trial?

There is no requirement for any trial membership.  I'm not sure if you are referring to the optional third party software, which you can opt-out of, or the optional software trials on the completion page, that displays after Flash Player is installed successfully.

If Flash Player installed without error, it's installed successfully and you most likely need to enable Flash Player in the browser. To enable Flash Player in the browser see:

For Internet Explorer, see Enable Flash Player for Internet Explorer.

For Firefox on any OS, see Enable Flash Player for Firefox.

For Safari on Mac OS, see Enable Flash Player for Safari.

For Google Chrome, see Enable Flash Player for Chrome.

For Opera, see Enable Flash Player for Opera.
