| The Revit LT 2026.4 Update does not support uninstall. Once Revit LT 2026.4 Update is applied Revit LT 2026 cannot be reverted to its pre-update state. |
| Installing this update from an outdated version of Autodesk Access may cause Revit LT to become unresponsive at 97%. When this occurs, the Revit LT Update components are fully installed but the update process does not complete. If you encounter this problem, restart the workstation, update Autodesk Access, and run the Revit LT Update again. You can obtain the latest version of Access from: https://www.autodesk.com/products/autodesk-access/overview. |
