No sound in Halion Symphonic Orchestra with FL Studio

Hi, I’m using FL Studio and have now Halion Symphonic Orchestra installed and registered - so no registration issue.

When I load it as a VST-instrument into FL Studio, there would be no sound - ONLY if I click with the mouse onto the keyboard of the Halion Player. Does anybody have an idea of how to solve this problem?

Thanks in advance!

Problem solved! I somehow got a VST2 and a VST3 version of HSO. While the VST3 doesn’t work properly, the VST2 does.
