Flair tutorial file gives missing PLOTGEOM.STORE error for 2D projections

Running and Runtime Errors
1

With an unmodified “tutorial.flair” file from the Fluka Tutorial web page (Official flair site) and running Flair 3.3.1, 2D projection plots fail because a PLOTGEOM.STORE file is missing. 1D projection plots do work.
For example, following the instructions in the tutorial to plot the “Red” geometry (step 5. Geometry Plotting), the output file below with the error is generated.
Is there a bug in Flair 3.3.1, or is there a way to fix the tutorial file so 2D projections can be plotted?

That file gives me 2D projections of the geometry without any problem.
It looks like you are mixing up two different FLUKA installations, namely /opt/FLUKA_CERN/fluka4-4.0 and an old /usr/local/flukagfor.

Thanks for noticing the usage of the two FLUKA versions. We have two versions of FLUKA on the machine, but I don’t know how Flair was able to access them both at the same time.
I de-installed and re-installed Flair, and the problem went away.
