Try this: Open your folder where your installers are stored (dont click on the installers just yet) leave the folder open on your desktop, then log into your account on this website (do NOT logout, stay logged in & DO NOT CLOSE your browser) then go into your open folder & select the installer by right clicking on the installer & select "run as administrator", a box should appear & youll need to reinsert your username & password into the box, it`s a bizarre way of doing things, but hopefully this will solve your problem.
Good Luck, I hope this helps.
