Installed fine on my Toshiba Windows 10 Laptop .. But the UI is horrendous .. Please bring back the one from the prior version. At least that was easy to read and navigate. I used the Full Off Line Installer for the update. Not sure if it used a 64 bit install or 32 bit (laptop is running Windows 10 Home 64) ... Has anyone tried to see if this will install on XP (some us, like me, just use: File, Web, Behavior Shields, Rescue Disk) ? ? ?
