How to Enable Adobe Plug-Ins
The Adobe plug-ins for web browser are designed to make your Internet experience both easier and more satisfying. Adobe makes a variety of plug-ins, all designed to work in conjunction with an Internet connection, like Adobe Reader and Adobe Flash Player. If you want to enable these or any of the other plug-ins designed by Adobe, you'll need to download them (for free) and install them on your computer.
Go to Adobe.com (see References section).
Click on the "Get" button that represents the Adobe plug-in you'd like to enable on your computer. The four consumer-level plug-ins that Adobe makes are Reader, Flash Player, Shockwave Player and Air.
Click on the yellow "Download Now" button on the page that appears. This will download the installation file for that plug-in to your computer.
Double-click on the file from Step 4 to launch the setup utility. Click "Next" a few times to install the plug-in. Once the setup process is complete, that Adobe plug-in will be properly enabled on your machine.
