Cubase 11 can't find HALion Sonic SE 3.4.10-Instrument

I recently updated my Cubase 6 to Cubase 11. I was confused, because i couldn’t find the other sounds i downloaded in the download manager. Because of that i thought that i had just installed it in the wrong order, so I deinstalled the programms and folders and now after I reinstalled everything it won’t find the HALion Sonic SE 3.4.10. Looking back at my actions it was really stupid to just deinstall the program and even the folders, but I learned and want to fix it now. I’m very frustated and would appreciate help.

Just download and install Halion Sonic SE from Download Assistant. Or you can download it from here:
