monitor lost connection with solver

hello,

One of my students has a flow problem, more, i guess a hardware problem.

Every time he starts a flowcalculation he immediately gets the error: "monitor lost connection with solver"

This happens with his models, a new model and a part i have modelled.

I tried switching off the firewall, accessing certain *.exe through the firewall, running solidworks as administrator

repairing SolidWorks but nothing seems to work.

Does anyone have another idea to solve this??

thx

Theo
