You can drag 100+ SolidWorks assemblies into AutoCAD, and the converter will process them overnight.
As of late 2025, Longbow Software has pivoted to a subscription model for their "Pro Cloud" service. However, because the local desktop converter for AutoCAD is based on open-source libraries (Open Design Alliance), a dedicated team of developers continues to release free, updated versions via community repositories.

The Open Design Alliance (ODA) offers a free command-line tool called the ODA File Converter.
The search for a "Longbow Converter for AutoCAD free updated" is ultimately a dead end for legitimate software. The Longbow Converter remains a premium tool for a specific niche: keeping old versions of AutoCAD alive on new Windows operating systems.
If you simply need to convert file formats (e.g., turning a 2024 DWG into a 2010 DWG), Autodesk DWG TrueView is the answer you are looking for—it is free, updated, and safe.
However, if you absolutely must get AutoCAD 2013 running on a Windows 11 machine, Longbow remains the industry standard solution, but be prepared to pay for a license to access their updated technology securely.

If you are using a purchased version of the Longbow Converter, follow these standard steps from the Longbow Software Blog:
Unblock Downloads: Before installing, right-click the downloaded ZIP file, select Properties, and check the Unblock box to prevent Windows SmartScreen issues.
32-bit vs. 64-bit: For 32-bit AutoCAD installers, use the first tab in the app. If you have a 64-bit installer for an older version (like AutoCAD 2010), right-click the tab to switch modes.
.NET Framework: Ensure .NET Framework 3.5 is installed on your PC, as legacy AutoCAD setups frequently require it to run.
The "Reviver" Step: After the initial installation, you must often use the "Old AutoCAD Program Reviver" tab to target the newly installed folder (e.g., C:\Program Files\Autodesk\AutoCAD 2010) and click Fix Old Program to ensure stability. Common Issues
Cursor Lag: Some users have reported cursor jumping or instability in older versions like AutoCAD 2004 when running on Windows 10.
Install Paths: For some mechanical versions, it is critical to install to a short path like C:\mdt2006 rather than the default Program Files folder. Longbow Software
