What is the authentication code?

There are two codes "registration" the first one you input during the install then the "authentication" ether have to call in & get it or log on to the internet & register, then they give you a code that says that its not pirated, if you have icon on your desk top, "you've installed it" right click & go to "properties" then click on "open file location" look for "register" or "license" it is a "EXE" file click on one of those it might get you were your going, if by chance you have the code & it came from a "kick" or "bay" type share site? you messed up a step during the install, you'll have to uninstall & run ccleaner, "read everything carefully" & retry, if its legit ("I'm not assuming anything" or saying its not. "god know Ive needed to share a file or two, I always block it with the firewall ") also try opening the application, if you can get to the interface, go to the help tab far right & look for register or license & try that..
