: Locate the downloaded EXE file (e.g., AutoCAD_2023_English_LP_Win_64bit_dlm.sfx.exe ) and double-click to start.

You must have a fully licensed and active installation of AutoCAD 2023 or an applicable 2023 vertical toolset (such as AutoCAD Architecture or Mechanical).

The language pack must match the exact year version (2023) and product type (e.g., standard AutoCAD vs. AutoCAD LT vs. AutoCAD Architecture). An architecture-specific language pack will not work on vanilla AutoCAD.

If issues persist, contact Autodesk support or an authorized reseller for assistance.
