Important Release Notes
LIRA-FEM 2026 requires Microsoft .NET Framework 4.8 to be installed.
If this component is missing from the system, the LIRA-FEM installer will automatically offer to install it before continuing the main installation process.
After installing Microsoft .NET Framework 4.8, a system restart may be required. In this case, restart your computer and then run the LIRA-FEM 2026 installation again.
On current versions of Windows 10 and Windows 11, this component is usually already installed. On older or outdated systems, it may be installed automatically by the LIRA-FEM installer.
