The package you've linked is designed to be copied and run from an ST hard disk. Unfortunately it's just too big to run from any floppy format the ST can handle.

If you have an ST hard disk and want to copy the files across via floppy, you'll need to prepare a special 720KB disk format. There are also several better options for transferring files to the ST - including serial cable, Ethernet, and even SD card. You can find all of this explained here.

If you want to copy a single file larger than a floppy's capacity, you can use ARJ/UnARJ to split it up and copy in smaller chunks.

If you don't have an ST hard disk at all, your best bet it to find an original copy of STOS. It first shipped on 3 separate floppy disks and could be run directly from them.
