In 2013, with the release of Act! v16, TopLine Results Corporation implemented a new upgrade policy for TopLine add-ons. TopLine add-ons purchased prior to August 2013 must be upgraded to be compatible with Act! v16 or later versions of Act!. For Act! v20, there is no TopLine add-on upgrade required if your TopLine add-on was purchased after August 2013 or the add-on was already upgraded for Act! v16. For example, if you are currently using Act! v19 with two licenses of TopLine Designer, you would pay no upgrade charges for Designer when you upgrade to Act! v20.
This upgrade requirement primarily affects customers who purchased TopLine add-ons prior to August 2013 who now wish to upgrade their Act! software.
