Are you upgrading from Lightroom 6 or CC 2015? (Check your version by going to Help>System Info.) If so, watch my video tutorial on how to upgrade to Lightroom Classic CC.
Otherwise: if you previously were prompted to agree to automatic updates and if you agreed, then go to Help>System Info to verify that you are now using version 8.3. Otherwise to update, go to Help>Updates, and in the CC app that opens, on the App tab click on Update next to “Lightroom Classic” (NOT Lightroom or Lightroom CC 2015.) If the update is not listed in the CC app and if your operating system is supported by Classic CC 8, click on the three dots in the top right and choose Check for App Updates. If it’s still not there and it’s the day of release, then try later. Otherwise try signing out and signing in again.
Because the app name has changed to Lightroom Classic from Lightroom Classic CC, your Lr dock or desktop icon will most likely no longer work. Remove it from your dock or delete it from your desktop, then on Mac in Finder go into Applications, open the Lightroom Classic folder and drag the application to your dock. On PC, in File Explorer go into Program Files, open the Lightroom Classic folder, right-click on the application and choose Send to Desktop (and/or Taskbar).
I don’t have any indication that things won’t go smoothly with this update; that said, it can’t hurt to wait a week to see if others experience issues, unless you need the update urgently. If I hear of serious issues with this release I will post them here in this section – please check here rather than emailing me.
UPDATE May 31: Some Windows 10 users were getting an error when exporting or using publish services. This has now been fixed in the 8.3.1 update released May 29.
