After including only 5500 of them, it works… so that is probably good. I guess the code is in flux there, but if it is a upcoming vtkmodules, it appears to be good that is now supported automatically already. Old vtkmodules apparently had no DLL code at all, or it was not really needed, not sure now, but there is no config to conflict with (plugin and yaml config for DLLs), so I assume it never worked on Windows, but I think it does, but this will need to be kept in mind, should this ever come up.

Thanks, this was helpful. Generally I want Nuitka to run where Python runs, disregarding how bad an installation it is, because those bugs sometimes highlight weaknesses in our code, that will also show in other more legal situations later or reveal more general problems.

Yes, now I got that file, but it wasn’t giving the error. But it seems it wants to include 6000+ DLLs now, something is awfully wrong there, but maybe on another day, this is pre-release software. The good news is I guess that the delvewheel code was working just fine, lets see if it runs. But whatever this is, seems absurd.
