Upgraded Halion Sonic SE 3 - missing content

Hi,

i installed the latest version of Halion Sonic SE 3 earlier (version 3.2.15). When i launched Halion Sonic SE 3 after that, it reported some missing content. I found the content it reported missing later in the Windows recycle bin. It’s the following VST Sound content: https://1drv.ms/u/s!Asq_J3FOGuuFkwty9qV_Fp39O3uF

Now i’m wondering, why does that content get removed when upgrading Halion Sonic SE? Also, is that content essential for anything in Halion Sonic SE?

Hope someone can tell.
