I know you do not have the game anymore, but to tag some thing you need to right click it and click on Run AS. The pop up window will give you the Administrator option. Also the SM you found is the EXE file. The full name is SM.exe, but the .exe is left off the visible name. If you pick the list option for the directory files, you will see the .exe, and other file endings like .png, .bat, .dll, .sma and others. Good luc k in the future.
