That worked, thanks for the very good help

Wow, thanks for fast response 64Bit Version Build Number:17625 Tho it most likely don't matter at all, on my computer it was under menu-help-about, but i assume it is the same.

Installed ironcad as an evaluation and tried the multiphysics part, followed some guides and youtube videos. the problem i get is that solve dll seem to be missing. The error message i get is: Error! Cannot load solver DLL file. Please check your installation! Error found... Process error encounterred! Any ideas what i can do to fix it?
