HALion Sonic SE content messed up after Halion Sonic trial

To keep it short, I’ve tried HALion Sonic 30-day trial and downloaded and installed all of the content accordingly through Steinberg Download Assistant.
Trial has ended, but I keep getting this message and I don’t know how to remove HALion Sonic content.
Any help would be appreciated, thank you.


Uninstall HALion Sonic content by using Windows uninstaller, please.

Hey. thank you for your response. I have tried reinstalling HALion Sonic SE and reinstalling Cubase, both with no luck.


The message you see is not about HALion Sonic SE, this is about HALion Sonic. So you have to uninstall HALion Sonic (and keep HALion Sonic SE). You can also remove all *.vstsound files manually with the HS in the name (not HSSE).

Thank you, this fixed it.

I removed all of the .vstsound files which included HS_ in their name from following locations “C:\ProgramData\Steinberg\Content\VST Sound” and “C:\ProgramData\Steinberg\Content\HALion”.

They should really either include these files in Halion Sonic uninstaller or find a way to inform people who are uninstalling the program after trail.

EDIT: Apparently not all files named HS_ are Halion Sonic only. Had to reinstall Halion Sonic SE and Cubase Halion Sonic SE Content to fix this.
