Just a short question about install on another computer

Hi!

So the 777 will most likely be released next week around wednesday. That is the day that my wife, my daughter and I are going to our parents for a few days.

My dad brought me to flightsim and he has made a home cockpit. So....if I buy the 777 next week, can I install that on my fathers computer and when we leave deinstall and reinstall at my home?

I seriously don´t know if I can wait all those days with the aircraft at my fingertips without trying to test it.

Will there be problems, when I activate the product at home after installing at my dad´s pc?
