Download Lightroom Update packages

Hello,

we are using the Lightroom 6 Desktop Edition and wondering if there are no separate Update packages to download (e.gh. for 6.4) anymore? With Lightroom 5 I was used to download only the update once and then installed the downloaded file on all our Computers. Since LKightroom 6 I am dammed to download the update on every single Computer (and we have 3 licenses installed on 5 machines) seperatly?

Is there still a way to get the update package as separat download?

Thanks,

Chris
