On the following operating systems:

• Windows Server 2019
• Windows Server 2022
• Windows Server 2025
• Windows 11
• SQL Server version 2019 or later

you'll need the username and password of a local administrator if you're not already logged in as a local administrator on the computer.

🛈 Note

If Windows updates on the system are not up to date, you may encounter issues when installing the new .NET Framework version.

To install Lexolution on a server or workstation, the following requirements must be met: - .NET Framework 4.8 is installed.
If the required .NET Framework is not present on the computer, the setup will install the appropriate .NET Framework before installing Lexolution. - WCF communication between the Lexolution client and server uses TCP, and the TLS version used for communication is determined by the operating system. The TLS version for TCP can only be set via the operating system, for example, through group policies, security policies, or the registry. Lexolution supports TLS version 1.2. - Microsoft Office 2016, Microsoft Office 2019, Microsoft Office 2021, Microsoft Office 2024, or Office 365 (Word on workstations and terminal servers) is installed and configured. - Microsoft SQL Server 2019 / 2022 or Microsoft SQL Server 2025 is installed on the database server. - The Lexolution delivery database is set up on the database server. - The Lexolution reporting database is set up on the database server. - The STP.Updater client is installed on the workstations.

Please have the following information ready: - The name of the server where the STP Lexolution Server service will be installed. - The TCP port number that the Windows service STP Lexolution Server will use on the Lexolution server.
If you don't specify otherwise during setup, port 8000 will be used. - The name(s) of the server(s) where the two Lexolution databases are located, the names of the databases, as well as the username and password for the database user. - The name of the server where the STP.Updater Server service will be installed. - The TCP port number that the Windows service STP.Updater Server will use on the STP.Updater Server.
If you don't specify otherwise during setup, port 8017 will be used.

Please set the check frequency for the STP.Updater client.

Make sure your firewall does not block the ports used by Lexolution on the server and workstations.

Make sure your firewall does not block the ports used by the database on the server.

When the STP.Updater client starts, it will automatically check for available updates.
Depending on the option set in the updater, the STP.Updater client will automatically notify you of available updates at the specified intervals.
If updates are found, you will receive a notification.
You can choose to install the update or cancel.
At the next check, you will be notified again about the available update.

If the STP.Updater client is not present on the computer, the setup will install the appropriate STP.Updater client before installing the Lexolution client or Lexolution Word Add-In.

Make sure you have access to all relevant installation files. You will need access to the STP GmbH download directory for this.
