Follow these instructions to solve issues around installing/running your legacy AutoCAD LDT 2002 on Windows 11. It requires the purchase of our Longbow Converter App which provides the framework to allow your old AutoCAD to install and run natively on Windows 11.
NOTE: We currently only support US unlocked versions of 2002 on 64bit OS. European or locked US support 2002 is limited only to 32bit Windows 11.
Just before we start note that 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.
You must first install sp1, followed by sp2…
