i am sorry for the trouble, i tried to do what you said but i downloaded the file in this post.
i opened it and i said open with.....which did not work
i then saved it and tried both open and open folder...niether of them worked,i have no idea what i am doing wrong.
P.S. when i save the plugin, it is in a .dll and will not show up in ABRviewer
EDIT:
I figured it out
