Como instalo la libro de colores pantone en Illustrator?

Pantone libraries are no longer included.

There is still one version that you can download that has the libraries.

You can have multiple versions of Illustrator installed.

Install an older version of Illustrator: 2023 (27.0), this is the last version that has the old Pantone Color books.

In the Creative Cloud app select Apps > All Apps > Illustrator > click the 3 dots …  next to the Open button >  click Other Versions and select 27.0

Go the Illustrator 2023 Application folder > Presets > (your language folder) > Swatches > Color Books > and make a copy of PANTONE+ Solid Coated.acb and PANTONE+ Solid Uncoated.acb 

Keep them in a safe place and copy them to the same location in the Illustrator 2024 application folder.

If you have a Photoshop license, you can install Photoshop 22.2.

Then, open Photoshop 2021 Application folder > Presets > Color Books and you will find the PANTONE color books, so copy it to Illustrator's Color Books folder.
