Hello,

When you go to purchase a 1 year or unlimited subscription for iCagenda Pro, you will be directed to MyCommerce Share-it purchase order page.

After purchase validation, you will receive a confirmation email from MyCommerce with a temporary link to download the latest Pro version.
Just download and install the pro package zip using joomla extensions installer (do not uninstall the free version to not lose your data!).
Installation of pro will act as an updater from free to pro version automatically.

In the 48 hours, i will create a pro account for you at pro.joomlic.com with access to your pro profil, Pro ID Key and Pro ticket support.

Hope this answers your question ?

Best regards,
Cyril
