You say a friend transferred the files to you, but you downloaded it from the Ulead site too?
Don't put the installer file in the plugins folder. If it's still there, remove it. Make a new folder on your C drive and call it "Downloads" and put it there instead.
If it's an installer problem, maybe try this one. It works, just used it a couple days ago. (link removed) Save it to that downloads folder, and just run it.
