All minimum system requirements are based on a single-user environment (one Windows client user accessing a local database or one web client user accessing a hosted database) and do not represent requirements for optimum performance of your Act! implementation. 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.
Express is free, but limits processor use to the lesser of a single CPU socket or 4 cores. Memory is also limited to 1 GB, and the size of your data file cannot exceed 10 GB. For this reason, we recommend SQL Standard for any deployment over 20 users or 5 GB in size, allowing for growth. Individual performance may vary based on actual database size, hardware variations, and product usage.
