The Longbow Converter App is a tool that allows old versions of AutoCAD to be installed on Windows 10 and Windows 11. To do this, the process is split into two parts…
- Convert the installation media and install AutoCAD
- Once installed, convert the AutoCAD program files so they run as normal
There many versions of AutoCAD all with their own nuances therefore we had to create individual instructions for each AutoCAD version. To find your AutoCAD version specific instructions please use the “Search” box in the top left of this page. e.g.

The format of the search text is “Install AutoCAD <version> Windows <version>” Some examples of what to type:
- “Install AutoCAD R14 Windows 11” or click here
