"VirtualBox - Critical Error
Cannot create the machine folder ubuntu-16.04.1-desktop-amd64 (1).iso in the parent folder C:/Users/rodol/Downloads.
Please check that the parent really exists and that you have permissions to create the machine folder."
C:/Users/rodol/Downloads is the path in which I downloaded Ubuntu (named "ubuntu-16.04.1-desktop-amd64 (1).iso"). The file is still there while I'm trying to mount it on VirtualBox.
Any suggestion?
I'm not English and I know nothing, so please be patient

These are the files I find in the path C:\Users\rodol\.VirtualBox:
selectorwindow.log
vbox-ssl-cacertificate.crt
VBoxSVC.log
VirtualBox.xml
VirtualBox.xml-prev
