Me ajude por favor, estou começando agora a usar o App, não sei com abrir no computador e no celular so aparece LR como fazer pra usar o modo lrc e como abrir no computador?. Desde já agradeço.

Depending on what Adobe plan you purchased, you may already have the subscription that includes LrC. What plan do you have? Go to account.adobe.com, log in, and tell us the name of your plan shown there. My plan is the Photography Plan (20GB) as shown below

First you have to download the Adobe Creative Cloud software to your computer.

Then you install the software, open it, install LrC and then double-click on the LrC icon to open it.
