I am a student, and in my tech dept. there is a supervisors PC. Now I have managed to install the SubSeven client on this PC but I cant run the attack program from another PC because of "restrictions"

I have tried renaming it as notepad which works with nearly all other programs but with SubSeven it just says "eh, this should be called SubSeven, rename it", but when I rename it I cant access it.

What file holds the programs names that are let e.g. mspaint, enc99, notepad, powerpnt, wordpad, winword?

I have tried adding a new file type and use the program to open it with The attack program but this doesn’t work either
