which is the recc way to lic kis7. it comes with a activation code. should i convert that to a key to keep on hand or if i need to uninstal then reinstall do i just type the activation code again. would they key allow me to reinstall it more times if i need to.. i mean is the activation code locked in when i use it? or does it produce a key after activating i can save? thanks in advance sorry one other question i have.. since i bought three retail versions brand new sealed.. i want to use the first one for my three pc's for the first year, the second retail box for the next year and so on.. is this okay to do? or will the 2 of the 3 boxed versions i bought be useless. i bought three since they were free after rebate and i had 3 address' to send them to. thanks again..
