Hello,
Actually it would be better to have a compiler installed because when you want something specific for a case, you may program it. Many test cases have also specific programming (the file caeed FORTRAN FILE), so you would be very limited with only an executable.
So I am afraid that you will have to follow the instructions and try to install the whole stuff, it is not so complicated when it works, and you have already a lot of questions regarding installation answered on this forum.
With best regards,
