Please see also following installation log from Output Window:

Is there anybody who has an idea how to resolve that issue?

Tanks in advance!

Apologies - that was a bug. Should be fixed now!

Hi Oliver,

Great! Updated and now dependency checker is passing except for HISA. Since building/installing takes some time I figured HISA is not needed to mesh so went ahead to that step. Here is my output. I am following along with the tutorial 1 on http://www.opensim.co.za/training.html
Some things are different in my version UI but most steps are the same. I also tried meshing with different element sizes and different meshers. Please see below for cfmesh error

Could you upload your .fcstd file from which this can be reproduced?

Yes, it works now.

Thanks for your quick action! That's the advantage of an open source project!

The element size you are using (50mm) will generate a tremendously fine mesh. Try starting with 800mm and go from there. If you have too many cells you can end up exceeding the size of the 32 bit label type in OpenFOAM - possibly what's happening here.
