All minimum system requirements are based on a single-user environment (one computer accessing a local database). In a shared environment, Act! Pro is designed to work with up to 10 users and Act! Premium is designed to work with more than 10 users. Recommended server system requirements are for environments of more than one user. Customer registration and activation are required and you must purchase one license of Act! per user. Your system must meet the minimum requirements to be eligible for technical support.
Act! Premium uses SQL Server® 2008 R2 SP1 Express or your existing installation of SQL Server 2008 R2. Act! has also been certified against existing installations of SQL Server 2012 and 2014. If you would like to use a different edition of SQL Server other than the one provided, please consult Microsoft documentation for specific requirements for that edition.

SQL Express limits CPU cores/sockets, memory used by SQL and the size of your data file to 10GB. For this reason, we recommend SQL Standard for any deployment over 20 users or 2GB in size. Individual performance may vary based on actual database size, hardware variations, and product usage.
