I'm evaluating Wolfram SystemModeler and I want to explore its capabilities together with Mathematica. Unfortunately, I don't manage to get WSMLink working. In the notebook I'm using I typed

Needs["WSMLink"]
`

and pressed Shift+Enter. Mathematica gives me this error message:

I'm new to Mathematica and I don't know where I can start fixing my problem. I checked and the file C:\Users\Carlo\AppData\Roaming\Mathematica\Applications\WSMLink\Config.m does not exist on my computer. Do you have any idea how to fix this?

Hi Carlo, Welcome to Mathematica.SE! I'm afraid I don't have much experience with WSM myself (just downloaded an evaluation copy a couple of months ago, and it's expired now). Given the path name I gather you're on Windows. Did you follow the normal installation procedures and did you use the suggested paths? – Sjoerd C. de Vries Oct 16 '12 at 15:21
Thanks Sjoerd, I used the suggested paths but as halirutan pointed out below it seems something with my configuration... – carlo Oct 18 '12 at 15:57
