Installation/Activation question

I was wondering…

I have a system backup that I made earlier in the year before I installed unity (the first time) and used the system restore option not too long ago. Then reinstalled unity again after the system restore. So i was wondering, if I were to do another system restore, would I not be allowed to install/ativate unity again?

ps I have installed unity twice on the same laptop (once before the system restore and once after) and the free licence version.

You will be able to reactivate your free Unity on your restored Unity. Should not be any problem at all. If any thing bad does happen, just drop the support team and email.
