e2p219@gmail.com 0 Report post Posted July 29, 2020 Switched to a new computer and trying to activate Nitro Pro (12) on the new machine. Went to deactivate on the old machine first and got a -20:error - Invalid license number error. Also tried activating on the new machine without deactivating first and had the same issue. Both copies are version 12. Share this post Link to post Share on other sites
