Unable to create support case

I try to create support case, and it wants a model number, but there is no place to provide this. Anyone know how to use Acronis on USB drive? I am trying to replace laptop drive, and cannot put 2 drives in laptop, have to use USB

I’ve always used acronis with USB for backup/clone/restore functions.
Have you setup the usb drive? Has windows allocated a drive letter?
Same questions if you’re using the acronis boot disk.
