How to move a photo-edit program?

from w
I have a Photo-edit program on an old computer and now that the Fiji Friendship Club Inc have been given a lovely newly refurbished computer with lots more space, I want to move that program/or copy that program to the new computer. We picked this one up at the Brotherhood of St Lawrence in Footscray and it's a gift to our ethnic networking group from the Victorian Multircultural Commission to share with our members in Geelong. How do I do that? I don't have Photo-shop and don't intend to get it as I would never get any housework done then!
