Every time I try to download, I click on the install link and go to an advertising page for CC. I click on the download link on that page, get back to the install link, click on it, and go back to the advertising page. I have tried 4 different browsers on two Macs running Mavericks and get the same result. This endless web loop has been happening for over a month. I have given up on these Adobe products.
The install button downloads a .DMG file (most likely saved to your 'downloads' folder unless you changed it). You would then need to double-click the DMG to uncompress the actual installer and execute that.
Alternatively, you can use the off-line installer: Flash Player Plugin for Mac
