Open the registry editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows
Once there, check the LoadAppInit_DLLs key and make sure the value is set to 0.
To open the registry editor:
- Go To START type REGEDIT and hit the enter button on your keyboard.
- Then you can navigate as you would in windows explorer.

I've been plagued with this too and can't figure it out.
The only way I can get around it is to restore a known good version of the ENU folder.
C:\Users\%user%\AppData\Local\Autodesk\3dsMax\2018 - 64bit\ENU
I saved it off in another directory. Something in it becomes corrupt every other day or so. When it happens I navigate to the ENU folder and delete it. I then copy in the good one and I'm going again. It's a pain but it's better than reinstalling and then redoing all of my customizations.

Coming back to this old thread as it still seems to be relevant for 3ds Max 2020 in some cases.
Can someone please explain what the underlying cause is? What does that registry key do?
Searching for it, it sounds like a Windows mechanism to automatically load DLLs with every process but what has that got to do with 3ds Max? I even found references to malware, so some clarification would be really nice.
Thanks!
Since it a mxs callback exception, I would first try displaying all the registered callbacks to see what is registered:
callbacks.show()
Compare that to the output from a good max install and see what the differences are.
If occurring at startup, then possible places a bad callback could be registered are from 3rd party plugins, .ms/.mse files in the plugin folders, or a persistent callback registered within the maxstart.max file.
I just added a task to add better messages when an exception occurs in a callback, so you would know what the callback being run is.

Thanks Larry!
In fact the issue I am investigating has the same error code but it is not related to a callback (is it?):
-- MAXScript ExecuteMAXScriptScript Exception:

The MXS stack trace points at a line similar to this:
fileproperties.addproperty #custom "somepath" someStr
Why would an addproperty call cause this?
