Can I run my 2 Windows forums on single Xenforo Product key?

Hello team members I have 2 domains i need to start community discussion on them. Can i use single license code on my two domains?

 

let me check these point

 

after reading the pre sales Faq i come to the point that i cannot install application software on 2 domains. As far as my webistes forums are concenred now i will buy 1 license to it and next one i should go with free forum application.
