I have recently purchased LR6. I now have 4 versions of Light Room on my computer.
Question: Can I remove older versions without loosing photos or upsetting the running of the latest version?
Yes, you can uninstall older versions of Lightroom if you are satisfied with the current version.
This would not affect the current version or the catalogs.
Thankyou you for the prompt reply and advice Chetna, I can retrieve many Mgs of space.
Glad to help.
