I downloaded the Vienna Assistant, set it to download-only-mode, and attempted to download a library.
The software informed me that my hard disk only has 1.01 TB, and the 28.69GB download will not fit.
Finally I got lucky and tried setting a path for the "Default library location" (which I had left blank, because I was just planning to do the downloads for now). After that, it decided that it could indeed squeeze its 28.69GB into my TB.
Not very informative error messages, VSL... 😐
Cheers,
Jane
