We don’t charge for updates until we release a full unit incremental release. For example, upgrading from Banktivity 5 to Banktivity 5.6.6 is free, while 4.x to 5.x requires purchasing an upgrade license. We do offer upgrade pricing, normally at half off the full version price.
To download the latest version, go to the IGG Software website and click the “Download” button. The downloaded version will work in trial mode if you are not registered, or it will recognize that you already registered and you will be ready to go! Downloads can also be obtained here:
