ok right so im trying to get whdload working on my amiga 1200, which is proving harder than i thought i keep getting errors and problems i will list the errors im having and how exactly im doing what im doing hopefully someone will be able to help me

.
first of all i had a problem with the installer but i have fixed this one by copying "installer" to c using a shell command.
left in my whdload folder on my floppy disk are:
install
installer
c
s
docs(i think)
if i run install i get a command box up with the word install typed in it(just to clarify is this normal) so i hit return and out pops an error message:
"error: file is not an executable
error: returncode 10"
can anyone help me on thsi please?
EDIT:
i now get the error "unable to open script" anyone know how to fix this thanks
