So i tried to take every steps, even after trying to re-install Virtualbox but it still give me the same notice when reaching full finish of the appliance which written below:
Failed to import appliance D:\New folder (2)\Whonix-XFCE-22.214.171.124.ova.
Result Code: E_INVALIDARG (0x80070057)
Does anybody has the same problem? Please give me some advices! Thank you so much!
