Geometry Viewer problem

[Junjie_Zhang]

Dear experts，

When I open FLUKA, this error is displayed, and the “Geometry” page is not displayed properly.

Is there a mistake in the installation process? How can this problem be solved? Does the “Geometry” not open normally have any influence on subsequent calculations?

Dear Junjie,

did you install the flair-geoviewer package as well?

Cheers,
