New Kaspersky Plus, Windows 11 and Autodesk Fusion 360

Recommended Posts

After much investigation it appears the roll out of the new Kaspersky Plus from Kaspersky Cloud has not gone smoothly for some applications. Plus has now installed itself without prompt on both my main machines, one being Windows 10 and the other Windows 11.

The issue I have discovered is incompatability between Kaspersky Plus and Autodesks Fusion 360, however, this appears to only be the case on Windows 11; it seems to function correctly on my Windows 10 machine. This has resulted in me having to pause Kaspersky protection everytime I wish to use Fusion 360 on the Windows 11 machine, which is not exactly what I would prefer, or what I was hoping to get when I purchased the Kaspersky product.

I have tried multiple of the historic workarounds for this, such as adding the various Fusion 360 folders to the exceptions list (Yes, I am aware of how to do this correctly as I use it extensively during software development procedures.) Although the issue persists, whereby Fusion 360 will inform me there has been an access violation in "NsBase.dll". The product works fine (and has done for many years) on both my Windows 10 machine with Kaspersky Plus running, and on the Windows 11 machine but only if I disable this new Kaspersky Plus.


Any help, suggestions or feedback would be most welcome, especially from Kaspersky themselves as there appears to be little knowledge out there on this topic as of late in general.

Hello @Dreamz


  1. On the Windows 11 machine, in Kaspersky Reports, are there any Autodesks Fusion 360 related errors? 
  2. Please log a case with Kaspersky Support; on the support page select either Chat or Email, then select Application malfunction, Other template; Support may need logs, traces & other data, they will guide you; include any screen images of the error & a detailed history. 
  • If you do log the issue with Support, please share the outcome with the Community, when it's available? 

Thank you?
