Yes, for Windows (since you referenced an exe and those utilities, I am presuming that is the OS) the installer adds DLL's and OCX's so that the everything works. I think this may be limited to the utilities with user interfaces like EP-Launch and IDF Editor. They probably won't work if you don't use the installer. You might be able to use the EnergyPlus.exe directly, I'm not sure if that depends on anything that uses a DLL.
