Um, an FXhome preset pack is something totally different which is not
necessary to run the full version of Clab. It is an option allowing you to import presets
from the FXhome site, put there by other users. (Might want to check it out, by the way...)
To download and install the full version, I believe you go to Downloads and Key Files
and...well...download it. And you know the thing that says (!) Install on one system only! That means, install on one system only
And btw, just ask if you want to know how to download presets.
