Hi @sheth

You may want to download the ParaView version without MPI in the name, from: [https://www.paraview.org/download/](https://www.paraview.org/download/)

Best,

Hello Westphal.  
Please add a little more.  
Does your comment mean that choosing the MPI version was inappropriate? Does it mean that the MPI version is not working well?  
thank you.

It means that MPI is not installed on @sheth computer, and installing MPI is necessary to use the MPI version of ParaView on Windows as the download page states:
