I am afraid that there is no upgrade route from a single license to a version 6 or a version 7 Home 4 pack. If you have purchased the single license within the last 30 days you could e-mail 'sales (@) macrium.com' and ask them to refund your single license so you can purchase a Home 4 pack, but only a version 7 Home 4 pack is now available to purchase on the website.
I suppose if you purchased a little more than 30 days ago you can ask sales if they can help but a refund may not be forthcoming.
Always quote your license key when contacting sales.
