OpenVAS credentials download empty package empty (0 bytes)

Related: https://forums.kali.org/showthread.p...empty-packages
Hi,

Not sure if this is a Kali or an OpenVAS issue - I suspect the latter - but after extensive searching all over the 'Net, the only reference I found was the one above (yes, 3 years old; no relation to me). That question got no reply, so I'm trying again.

My issue is that when I'm in the OpenVAS GUI (Greenbone Security Assistant, or GSA), and I ask to generate an 'exe package' for Windows authentication, the file is empty; 0 bytes.

Any OpenVAS on Kali users out there?

Thanks!

Cheers,
-Paul
