Lightroom 6 has been discontinued and is no longer available for purchase on Adobe.com. Consider upgrading to the Creative Cloud Photography plan to get the latest updates in Lightroom Classic CC and Lightroom CC, and ensure that the software works with raw files from the newest cameras.
When you serialize, or convert, a Lightroom CC 2015 trial with a perpetual license serial number, the branding of the app changes to Lightroom 6. Basically, you're converting a Lightroom CC trial to Lightroom 6.
The app and app folder found in the Applications folder (Mac OS) or Programs Files folder (Windows) are always labeled "Lightroom" with no version number:
If you sign in with an Adobe ID that has an active Creative Cloud membership associated with it, you don't see the serial number screen, as your Creative Cloud account is activated. For more information, see If you have an active Creative Cloud membership and a serial number for Lightroom 6.
Note: If you're upgrading from a prior version, have your prior version serial number handy to enter as part of the activation process. If you've lost your box and/or serial number—or can't remember the prior version serial number—sign into your account to view your registered product serial numbers. If you didn't register your product, but you still have Lightroom installed and licensed, you can retrieve your serial number from the following location:
- /Users/[your user name]/Library/Application Support/Adobe/Lightroom/Lightroom 5.0 Registration
Note: You may need to use Method 2 in Access hidden user library files in Mac OS.
- C:[your user name]\Program Data\Adobe\Lightroom\Lightroom 5.0 Registration
Note: On Windows, the extension is .LRREG.
When opening Lightroom for the first time after the initial installation, you’re prompted to log in with your Adobe ID. If you have an active membership plan associated with that Adobe ID (for example, Creative Cloud All Apps or Creative Cloud Photography), Lightroom is activated, and licensing with a serial number is NOT possible.
You can install your Creative Cloud apps on as many of your personal computers as you want. However, you can only sign in and activate Creative Cloud on two systems at a time. To switch to an alternate computer, simply sign out of one of your two previously activated computers. If you're unable to sign out of the other computers when you sign in, you are asked if you want to deactivate them remotely. You can start using the current system immediately. You can force an activation reset once every 48 hours; therefore, it’s preferable to sign out when possible.
If you have both a membership and serial number for Lightroom CC and want the option to enter a serial number with installation, sign in to Lightroom with an Adobe ID that does not have a Lightroom membership associated with it. Simply create an Adobe ID with which to sign in. Signing in to Lightroom with an Adobe ID that's not linked to an active Creative Cloud membership enables Lightroom to prompt you for a serial number.
If you recently canceled a membership, there may be remaining days on the membership before it completely expires. Continue to use Lightroom until the membership expires, and then follow the instructions in Convert a Lightroom CC trial to Lightroom 6.
