have decided to go with plan b install titan suite v7 as we dont need many bells and whistles and it works without registration

Hi we have 2 titan 1 dongles and i would like to put the software on multiple laptops
am i going to have to get 2 licence numbers for each laptop which could use either dongle ?
if so that would be 20 licences as we cant always guarantee which laptop will go on the job
many thanks
Chris
