.NET Framework features by Windows Server version​

The required .NET Framework version depends on your Windows Server version. The installer adds these features automatically where possible. If you're preparing your environment manually, make sure that the corresponding framework and the following roles and features are enabled:

Windows Server version.NET Framework versionSubfeature to enable

tip

If you cannot restart your server during installation, make sure to manually install all required frameworks and libraries before you run setup.

Additional software prerequisites​

During installation, the SEI installer checks for required Windows components and automatically installs any missing prerequisites. These include .NET Framework 4.8, Microsoft Visual C++ 2015–2019 Redistributable, ASP.NET Core 6.0.3, and the necessary IIS roles.

If you cannot restart the server during installation, manually install the following components before starting setup:

  • .NET Framework 4.8
    Required for installing both the SEI Server (Server - Win64.exe) and the SEI Excel Add-in (Excel Add-in – x64.exe).
    Download: Download .NET Framework 4.8
note

The Excel Add-in installer will automatically install .NET Framework 4.8 if it is not already present.

Additional libraries for Oracle database support​

To ensure correct data access when connecting to an Oracle database, install the appropriate Visual C++ Redistributable library based on your DLL version:

  • For DLL 121.2: Microsoft Visual C++ 2010 x64 Redistributable
  • For DLL 122.1: Microsoft Visual C++ 2013 x64 Redistributable
