Setup will do this for you anyway. SharePoint Calendar E-Mail Extension 3.0 is built on the 2.2.1 version of the sapiens.at SharePoint Framework. It’s very likely that you have 2.2 or 2.1 already installed. 2.2.1 is published for the first time with SharePoint Calendar E-Mail Extension 3.0.
Now you’ll need your license key. A trial key (30 days) is always available from the download button at the product page: /calendar-email-extension.
If you have no access to the internet the setup will not succeed. But you’ll find a file named unvalidatedSurety_Sapiens.at.SharePoint.CalendarEmailExtension[3.0].xml in the setup directory. The file is created during setup and is designated to support offline key validation. Take this file, attach it to an e-mail and send it to firstname.lastname@example.org. We’ll return the validated file plus instructions as fast as possible.
You’re now finished with installing the solution.
