Installing AutoCAD 2005 on Windows 11

Posted on by

Follow these instructions to solve issues around installing/running your legacy AutoCAD 2005 on Windows 11

IMPORTANT NOTE: Autodesk no longer supply License Activation codes for this version of AutoCAD. The best way is to transfer your existing license to the new PC but there are other options, we document them here

Ransomware Protection Windows 11 and AutoCAD

Windows 11 comes with a Ransomware Protection which includes Controlled Folder Access. 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.
