Dear All,

When I run the example “web-project-templates-master” in Windows gives the following error:

From VTK Forum.

If I install Paraview 5.9.0 solves?

Which is the master? MPI version?

3

Bug in paraview 5.9 release, use ParaView master.

4

Which is the master? MPI version?

The simplest way for you would be to download the nightly release of ParaView, but it is not available right now. It should be in a few days.

You could also build the superbuild yourself:
https://gitlab.kitware.com/paraview/paraview-superbuild

6

The MPI version gives the same error.

7

ParaView 5.9.0-RC2-Windows-Python3.8-msvc2017-64bit works?

8

How many days is few days?

Luis,
Lets say days, not weeks. Number is not determined, units are.
