Hi,
We purchased 2 licenses for avast! 4 Professional Edition and now one of the computers is broken. How can we move the license to the new computer?
Thanks.
Hi…
Just e-mail sales@avast.com with your information to get a “reprint” of your key if you haven’t saved the previous registration information. 
If you have saved it, just copy and paste the key into your new copy of avast Pro.
Best Regards…
If you saved the registration email (wise), you can use the registration key again on the replacement system, provided the use is restricted to 2 systems.
If you didn’t save it then follow ardvark’s suggestion.
I’m glad that I saved it. Thanks!
You’re welcome! Glad we could help.
Best Regards…
No problem, welcome to the forums.
