Hello Paraview community, recently I upgraded to v 6.0.1 and I noticed that calling pvserver by mpiexec prompts n times connection waiting messages. $ mpiexec -n 3 pvserver WRN - The configuration file has not been found, using default parameters. WRN - The configuration file has not been found, …

This is Intel MPI, not Microsoft MPI which would be what is expected and what ParaView binary for Windows supports. You need to either install Microsoft MPI (as stated in the download page: https://www.paraview.org/download/?version=v6.0&filter=Windows ) or compile ParaView yourself.

I’m not sure if I get the question correctly. I downloaded ParaView-6.0.1-MPI-Windows-Python3.12-msvc2017-AMD64.msi from www.paraview.org/download/ and followed the installation procedure using the default settings. Is there any specific setting that I must check?

Great, then this should work. Please share the content of ParaView About dialog (Help->About)
