Ransomware Protection Windows 11 and AutoCAD

Controlled folder access blocks applications from writing to your Documents, Pictures, Videos, Music, Public and Favorites folders. AutoCAD versions all the way to AutoCAD 2021 write to certain user Public folders and are therefore blocked by this feature. This can cause issues with all sorts of things including activating your AutoCAD license and even running AutoCAD. Ransomware Protection is an important feature of Windows 11 but it will affect your AutoCAD unless you allow AutoCAD and its dependent applications access to the controlled folders.

Using the Longbow Converter to install your AutoCAD

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…

  1. Convert the installation media and install AutoCAD
  2. 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
  • Install AutoCAD 2000 Windows 11” or click here
  • Install 32bit AutoCAD 2013 on Windows 10” or click here
  • Install 32bit Mechanical 2009 on Windows 10” or click here
