I cannot find the deactivating option in my lightroom 5.7, and I will install the lightroom to my new laptop. How can I do to prevent the activating issue in the new laptop?
There is no activation (or deactivation) mechanism in Lightroom 5 or earlier.
If you don't want Lightroom to remain on your computer for possible future use then just uninstall.
Thank you for your reply. It's really helpful.
