Install Public Build with DazCentral?

Hi,
I have a Surface Pro 7 tablet, and I've been unable to run the old Daz Install Manager - everytime I try to log in, the application crashes. I've submitted a support ticket but haven't heard anything yet. I'm currently trying out DazCentral which works OK but it always installs Daz Studio 4.12 and not the public beta. Is there anyway to get it to install the public build?

Never mind my first post. I reinstalled DazCentral a 2nd time and for some reason it chose to install the public build this time.
Daz Central shouldn't work for betas - it is a simplified/new user system, after all.
