NIS-2012 language support & account connection

I bought a NIS-2012 3pcs license key and would like to activate it.

 

2 question regarding that :


1. can i install the NIS in different PC with different language or 1 license (3 pcs) is linked to the same language ?
2. i installed the trial version with German wrongly and later installed in the english version  but when i go to my account it still says that i have a trail version with language English can i ignore it ?

 

Thanks
