Not sure you can. But Beersmtih comes with two licenses so as long as you have your license code, you should still be able to activate the copy on your new computer,. I just went through this.. Paid for Beersmith 2, installed on my desktop, then realized I really needed it on laptop. Just installed and actived with the same code on the new computer. If all else fails, email Brad at beersmith- He is great about answering questions for users. Good luck
