I can't access the EX100 archive link, says it's no longer valid. I've had a lot of trouble with 0.7.1a, every build, even ones which do nothing but apply updates seem to fail on VirtualBox. I try the original image (en_windows_10_multiple_editions_version_1511_updated_feb_2016_x64_dvd_8379634 : md5:a4fde74732557d75ffc5354d0271832e) and it works without a problem so it's not a VM issue. Anyway I sourced 0.6.6a from some other website [You must be registered and logged in to see this link.] and will try that
