  • “You cannot install this product on the current operating system”
  • “You are attempting to use a 32-bit installer on a 64-bit operating system”

Ransomware Protection Windows 11 and AutoCAD

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.

Visual Basic Applications run very slow in AutoCAD 64bit

Posted on by

If you use VBA inside of 32bit AutoCAD you will have noticed that it is around 1000x times slower when running the same VBA code inside of 64bit AutoCAD.

This is because AutoCAD 64bit ships with the 32bit VBA DLL in a separate out-of-process executable rather than loading the VBA DLL inside of AutoCAD itself. Therefore, a lot of marshaling is incurred communicating between the out-of-process VBA executable and 64bit AutoCAD.

Other issues you may be seeing: Run-time error ‘429’: ActiveX component can’t create object

Affected, all 64bit versions of (and variants of)

  • AutoCAD 2008 | AutoCAD 2009 | AutoCAD 2010
  • AutoCAD 2011 | AutoCAD 2012 | AutoCAD 2013
  • AutoCAD 2014 | AutoCAD 2015
  • AutoCAD 2016 | AutoCAD 2017
  • AutoCAD 2018
  • AutoCAD 2019
  • NOTE: Autodesk stopped making 32bit AutoCAD since AutoCAD 2020

The solution to slow running AutoCAD VBA

The best solution is to install 32bit AutoCAD on 64bit Windows, here are the affected versions along with their solution text…
