# cannot open WSMLink

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:

Get::noopen: Cannot open C:\Users\Carlo\AppData\Roaming\Mathematica\Applications\WSMLink\Config.m. WSMLink::cconf: -- Message text not found -- (C:\Users\Carlo\AppData\Roaming\Mathematica\Applications\WSMLink\Config.m)

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

I work with development of SystemModeler at Wolfram Research

Update: WSM 3.0.1 which fixes this has been released.

This is an issue when using a combination of SystemModeler and a trial version of Mathematica. Unfortunately it is not easily fixed, so you will have to wait for an update to SystemModeler which will include the fix.

You are right, I have a trial version of SystemModeler and Mathematica... I understand it cannot be easily fixed, but is there a workaround? What I really need is to evaluate are the capabilities of SystemModeler when I use it from Mathematica. –  carlo Oct 18 '12 at 15:20
Unfortunately there is no workaround that can be applied by you, short of buying Mathematica. –  Malte Lenz Oct 19 '12 at 5:48
