Hello,
Are You sure that Halion or any application using this libraries was closed during installation? - This could cause fault of future loading of library.
Please see my recent post. At least I think I did!
I’m on a Mac. I had the same problem. This is what I did to fix it, and I shared this with Steinbergs Level 2 Support.
Delete the Media Bay Program
Delete the Download Manager
Delete the Library Manager
Delete your library
Install your library to a different location to be safe.
This should solve it. I’m not sure what steps are necessary as I didn’t really like not seeing my sounds so I can’t retrace exactly what worked. I THINK it was the Library Manager and Deleting the Library. I moved it to be safe!
