You can automatically solve these problems using our Longbow Converter App, it fixes and manages the AutoCAD 2015 installation so that you can be up and running again… Follow these instructions:

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.

AutoCAD is running really slowly on my brand new computer…

Posted on by

If you have a brand new laptop and you have installed any of these versions of AutoCAD:

  • AutoCAD 2009
  • AutoCAD 2010
  • AutoCAD 2011
  • AutoCAD 2012
  • AutoCAD 2013
  • AutoCAD 2014
  • AutoCAD 2015
  • AutoCAD 2016

…and the performance of your AutoCAD is unbearable, then read on…

Most likely this issue is related to your new computer’s Intel Integrated Graphics – https://en.wikipedia.org/wiki/Intel_HD_and_Iris_Graphics

The Intel Integrated Graphics is a so called “feature” that bypasses your main graphics card to utilize the integrated graphics card save power – the problem is that it for AutoCAD it literally kills AutoCAD performance.

All you need to do is disable the Integrated Graphics feature in your computer’s BIOS setup (usually accessed by pressing a series of shortcut keys right at the start of your computer’s boot sequence startup) and you will be back to normal in no time – just know that disabling this power saving feature will use more battery power obviously.

I can’t comment on how to specifically disable it in your BIOS because it is computer specific, you will have to search for that yourself – I created this link to save you the time searching for “How to disable intel integrated graphics”
