Hello, I have just been given a canon 5d (the classic), without any software. I do have a Canon 50D with EOS utilities installed on my computer. however, when I try to connect the canon 5d there is no recognition. I am running Windows 7 home premium, 64 bit op. system. An error message came up saying no driver found, software not successfully installed. I have no software apart from the software for my 50D - any help would be SO appreciated...
