Missing sound archives Halion 7

I just installed Halion 7 to go with my Cubase 12 Pro, and it works well, except there is this error message for some of the VSTs: “Missing Sound archive”. I did let Halion to search for the files on all disks and all folders, but still nothing was found.
Please help!

Same problem now in Cubase 13 - - old mixer setups all lost and now these ‘Missing Sound Archives’.
