How to install Logic Pro X and point to the sound library already downloaded

[Samuele]

Hello

I am new to the DAW Logic Pro X... my problem is that I installed Logic Pro X on my MacBook Pro and now I would like to avoid re-downloading the entire sound library because I can copy it from my brother's computer who has already downloaded it.

Here's what I've already done:

1. I downloaded the essential files of the library to the internal disk, those that are offered when you start Logic the first time
2. I moved these files to an external SSD with the "Relocate Sound Library" function from the preferences menu
3. I replaced the "Library" folder on my external drive by copying all the files from my brother's library
4. I restarted Logic and saw that the library is not recognized, there are download icons next to the name of the presets

How can I solve it?
Thank you
