Which operating system do you have?

Did you hit the License this Product button and enter a valid 24 digit Serial Number from your original installation disks?

If you lost your serial number, you might find it by logging-in to in your Adobe account below.

Unfortunately, LR6 is discontinued & no longer supported. It's was not built to work on modern Mac operating systems  -- Monterey, Big Sur or Catalina which only support modern 64-bit apps.

Usually I'd say to contact customer service and ask for an Activation Count Reset, as that is the only thing Adobe customer support can now do for this program. However, I've not seen this error before so I don't know if it would work. Let's move you to the Account, Payment, & Plan forum, where you are more likely to get an answer for your question.

Also:

1. Do not, under any circumstances, post personally identifying information here, especially not your serial or license numbers. 
2. Do tell us what computer hardware and operating system you're using, as this can make a big difference.
3. Tell us of any troubleshooting you've already attempted.
