its not a .exe file its a .rar file ( im not really sure where did you get the .exe file from) but just in-case, re-download the file again and once you get the .rar file, download a program to extract the .ct file inside it (download winrar or 7-zip to extract the file ... just search for them on Google) and then if you have cheat engine installed you can double click on the .ct file and it should load the values automatically for you. if you don't know how to use a .ct file just look in the tutorial section, someone already made a tutorial on it.
