Licence use - expiration (multiple PCs purchase, but using 1 later than others)

Hi, sorry if this is already covered, I cant find it:

I purchased licence for 3 PCs for 2 years, but Ive only used 2 licences so far. If I use the (so far) unused licence on a new device after 1 year, will I still get 2 years from it or will it expire at the same time as the other 2 (the other 2 have been activated 1 year ago, so will all 3 deactivate in 1 year together?).

Thanks

it will expire same time as the others … since it is same license file that covers all pc

All licenses remain active from the date of purchase not when installed.
If you purchased a license on say Jan. 29, 2014 it will expire on Jan. 29. 2015.
Even if you did not install the license until Sept. 9, 2014.

ouch, ok thanks for the info!
