Hi,
I installed the ParaView executable (ParaView-5.13.0-MPI-Windows-Python3.10-msvc2017-AMD64.msi) on Windows. To set the path to the `CATALYST_IMPLEMENTATION_PATHS` I set it to the `catalyst.dll` located at “Paraview 5.13.0/bin”. However I still get an error during `catalyst_initialize`.
Does windows support ParaView catalyst and is this the correct catalyst implementation path.

You need to use the path to `catalyst-paraview.dll` and the like, not `catalyst.dll` itself (that path belongs in `PATH`). Though…this seems to be `bin` based on [this MR](https://gitlab.kitware.com/paraview/paraview-superbuild/-/merge_requests/1215). What error are you getting?

Thank you for your response. We cannot find the file `catalyst-paraview.dll` in the installation directory after installing the executable from the ParaView download page. Are we not looking in the right place or does the official ParaView Windows build not come with ParaView Catalyst?

That MR is fairly recent… @Lucas_Givord?

yes I add these missing dlls really recently, you need to download a nightly build on [paraview.org](http://paraview.org)
If you encounter any issue with that, let me know

@gsabhishek I was able to run the CxxFullExample with ParaView after adding the catalyst-paraview.dll, make sure to use the same python version between catallyst and paraview

@Lucas_Givord
I noticed that the ParaView Catalyst DLLs are missing in the latest Windows executable release (5.13.3). Is there a chance the Catalyst components will be included in the upcoming 5.14 or 6.0 releases?

Yes indeed, I merged it after the split for the 5.13.0 that’s why it was missing. It should be available in the next release
