I'm creating a new virtual PC on a freshly installed VirtualBox on my desktop, and only have 32 bit OS's available to choose in the General/Version section. Any ideas why? Does it matter? I have it installed on another PC & 64 bit OS's are available to me. I did install the Extension Pack on this computer & not the other.
My PC - Windows 8.1 Pro 64 bit with all patches, 20 GB RAM, trying to create a new virtual PC for my old PC (used Acronis to backup & convert the hard drive to a vhd).
Thanks for any suggestions.
