Adding the Italian Grand to a previous Ivory Install

[PhilAiken]

After running the installer to update the Ivory engine to 1.63, will I only need to copy over the Italian Grand Files and Receptorize them, since the other 3 pianos are already there and presumably Receptorized?

That's how I did it. I did not reload or re-receptorize the older pianos. Everything works fine.
