Microsoft OS and SQL Server Compatibility Matrix

Clinical is distributed with the free Microsoft SQL Server 2014 SP3 Express Edition.

  • SQL Server 2014 SP3 Express Edition has a maximum database limit of 10GB. For larger databases, a full Microsoft SQL Server is required. If you want to use a full Microsoft SQL Server product, consult the compatibility matrix below.
  • The SQL Server installation cannot be made on read-only, mapped, or compressed drives, and SQL Server setup via Terminal Services Client is not supported.
  • Ensure you have a minimum .NET 3.5 installed in order to run the SQL Server 2014 installation.
  • The SQL Server 2014 installation will install .NET4.0 automatically if not already present. This requires an active internet connection for the .NET4.0 installation files to be downloaded.
  • Always install the latest Service Pack.
