Installation Requirements

See Autodesk’s Product Support Lifecycle for support information.

AutoCAD LT must be installed on a 64-bit version of Windows that is currently supported by Microsoft. When Microsoft ends support for a Windows version, our support for Autodesk products running on that Windows version also ends. Install the latest Windows updates before installing your Autodesk product.

If Microsoft .NET 8 is not already installed, AutoCAD LT 2026 installs it. Microsoft .NET 8 requires a Windows version that Microsoft currently supports.
