OP, which Windows are you running? For all old setup.exe files you have to right-click them and chose a compatibility mode + run as admin and then install into a non-protected folder, that is a different folder than the suggested Program Files. Eventually you have to run the setup from a different OS, and transfer the files and registry entries. Win 7 and Win XP will read and execute the setup.exe.
With Win 10 you will have the most trouble with this game, it doesn't change buying it from somewhere else I think (and why buying the game a second time?), get your setup to run somewhere and transfer the files - and get rid of U-Play.
