virtualbox.org

here is what i get when i try it with the Import Appliance

this is the screen shot of the error and when i try to open it with the Import Appliance i can't see the file.

if i double click this kali-linux-2018.4-vbox-amd64.ova ( the file was to big to uploud) to open it i get the vinf_getopt_not_option error message.
and i can't get the list becaus i got no machine because it doesn't open.

i donwlouded virtual box. I tried to get a Kali LInus working on it but whenever i open a file for Virtualbox i get the message vinf_getopt_not_option and then it doesn't open. Anyone with a idea how this can happen?
