just purchased ver 5 with discount from ken.
I think version 3.66 was 32bit only, new version is 64bit?
Saw something about changing the reg file before import from 32bit to 64bit by adding the WOW64

1.I exported/backup settings from the about tab from the options
2.Exported each individual camera's setting from each camera general tab on the properties page

Do I need to De-activate ver 3 first

anything else?
