Building the library/vstsoundcountainer today went all smooth, installing it with the new Library Manager which was released with HALion 6 on two different computers was so easy, just double click on the vstsoundcontainer with the Library Manager open to register the library → done. Steinberg certainly improved the entire procedure of installing 3rd party libraries by 1000 milestones. So all I can do now is to wait for Steinberg to release the HALion 6 update 6.0.1
