Halion Sonic SE gone after updating from 2.x to 3.x

Hi all, since I’m mostly recording on HD and not working with virtual instruments I’m quite new to this. In short: I recently bought HSO to be able to provide my clients a virtual orchestra. Together with HSO the download assistant told me to install Halion Sonic SE 3.x
Now after installing Halion Sonic is completely gone.
Where am I wrong?
Thanks a lot in advance, Eric

I re-installed Halion Sonic SE 3.x now and marked the VST2- and stand-alone options. When trying to start the stand-alone version it says: “GetSystemMetricsForDpi” not found in user32.dll

Problem solved. I re-installed HSSE 3.1
