Since Act! is not an application which is sold in the Microsoft Store, Windows 10 S is not supported for Act! Program installations, nor is it supported for the installation of Act! Premium (access via web) and Act! Premium Cloud features, such as the Act! Mail Merge and the Act! Integration Service for Microsoft Outlook or Google.
