If you have FileMaker Pro (it's not free) , double click on the fp7 file and it should open. RW.
I have downloaded the trial version of Filemaker Pro. When I double click it, it opens up the editor (I think it's the editor).
I don't want to open the editor, I want to run the actual program.
Did you double-click the application you just downloaded and installed (it will likely put an icon on the desktop) or the file the teacher gave you? You need to double-click the file.
BTW: your teacher may be able to make a runtime version that the class members can run without needing to buy the Filemaker application.
