Hi,
Is there possible to install ParaView on Windows unattended from command-line, perhaps, with some command-line switches

Hello Raimond, welcome to the ParaView community.
You can download and extract our .zip portable version of ParaView, from the command line.

the exe is compressed with 7z, which is more efficient than zip.

I know this is an old thread but you can install silently by simply using /S
Uninstall is by running the uninstaller located in Program Files folder, again with /S

Downloaded “ParaView-5.11.0-MPI-Windows-Python3.9-msvc2017-AMD64” from the link. When running paraview.exe in the bin directory.
System error due to msmpi.dll error.
Is it due to downloaded the wrong file? or it’s not portable??
Thank you.

You’ve downloaded the MPI version of the binaries that need MSMPI installed on the system. You can use the non-MPI variants of the binaries for systems without MSMPI. i.e. use `ParaView-5.11.0-Windows-Python3.9-msvc2017-AMD64.zip` instead of `ParaView-5.11.0-MPI-Windows-Python3.9-msvc2017-AMD64.zip`.

It’s working now. Thank you.
