    DOES NOT WORK WITH 8.1!

    Please stop with the usual BS that any idiot probably has already figured out.

    Try installing the GA YOURSELF in VirtualBox 4.16+ and it will not finish because it will crash the entire VM! IOW, the host will be fine but the 8.1 GUEST simply aborts all to heck when you try to install the GA!

    And if I seem irritated, I AM!
