the licence for lightroom 6.14 seems to be cancelled after changing the cpu only. all the other components stay the same. How can I fix the problem?

Hi ​@defaultgm4z1su32vhl , Thanks for reaching out to the Lightroom Community Forums! Let's try a few things to see if we can get your Lightroom back up and running.

1. Check License Activation: Ensure that the license for Lightroom is still active. Sometimes, hardware changes can trigger reactivation requirements.

2. Sign In with Adobe ID: Open Lightroom and sign in with the Adobe ID that was used to purchase the license. This can help in reactivating the licensed version.

3. Reinstallation: If the issue persists, consider uninstalling Lightroom and then reinstalling it. Use the Creative Cloud desktop app or the Creative Cloud Download Center to reinstall it. This will ensure that the latest version is installed and may resolve any licensing issues.  https://adobe.ly/3VWhnHK

If none of these steps work for you, can you send your system info, a screen recording of the issue, and a numbered list of the exact steps needed to reproduce it? You can find your system info by going to Help > System Info, copying and pasting it into a text file, then attaching the file here. Thanks! ^CH
