Installataion of Halion Sonic SE failed

Yesterday I installed my Cubase AI that I could download thanks to byuing a UR22 USB audio interface. The zip file downloaded and unzipped correctly, but during the installation process a critical error was reported when the program was about to install Halion Sonic SE. Activation went OK, and Cubase AI could be started and used.

Now, where to go from here? Should I retry the install, will the program be intelligent enough to not protest about Cubase already being installed and activated and only try to install Halion Sonic, or is this a know bug that should be fixed in some other way?
