I am going to buy a new laptop as my old laptop having lot’s of problem. How can I transfer activated license from old laptop to new laptop?
It’s usually best to contact the developers directly for license related questions, though you may find your answer here.
FYI - you can install Bootstrap Studio on up to three computers, so you should be able to simply install it on your new laptop, enter your license key and activate.
(Note: the developers are off on weekends, so they will not respond until Monday.)
