LOSTANGEL57'S PROFILE

I just got a new laptop for christmas, and I love it. I used to have RPG Maker 2k3 on my old computer, and it worked perfectly (unfortunately that computer totally crashed). I downloaded it on my laptop, but when I tried to run it, I got the following error:
"Harmony.dll not found."
I've downloaded this "Harmony.dll" file 4 times, and I've tried both having the zipped folder and the extracted file in my RPG Maker 2k3 folder, and it still can't be found.
What do I do? did I do something wrong?
