One the flash player download window, unselect any optional offers
Click download, save, or install (depends on which browser you are using)
Please note that some browsers, such as chrome, have flash player built in and this is not required.
* Flash player must be installed for each browser that uses the plug-in. The installer does not search for other browsers you may have. For example if you use Firefox and an older IE the you would need to do this install twice. (New win8+ IE has Flash built in). IE will let you run the install directly. FF makes you save it first and then you have to manually run the installer.
