BS 2 and the double license

I bought BS2 for ipad and I'd like to install it in my notebook too using the second license. I don't know how to do this because i didn't receive a license key.

Please send me tips on how to install in my notebook.

Thanks, Celio.

Hi,
  The desktop and mobile versions of BeerSmith are separate purchases.
Unfortunately the app stores provide no mechanism to discount
or bundle the mobile apps - I can only set one price for everyone.
