DazCentral freezes(?) during DAZ-Studio Installation

harald-2432407

Hi there, I'm Harald from Germany and am using DAZ a couple of years. 

Now I downloaded DAZCentral to get DAZ Studio updated to version 4.15 (or higher) and the installation process seems to freeze after downloading the Studio file.

It says: "Installation will begin after previous installations". (see attachment)

Does it mean, there is something going on in the background that I don't get aware of? 

Any help is appreciated.

Harald
