Hi Jeremy: Just a guess, but it might be interaction SW-Word-SW. Can you publish a report in HTML format? That might help rule-out one variable.
I don't see an option to publish the report to HTML. I am using Simulation 2012 x64 SP2.0.
I have found that if I remove the model information tab, it will create the report but it won't include the results correctly. The other problem I had with this specific model is when I would use the include image for report, it would also crash Solidworks.
Just to note, I have used the report tool with plenty of other models and it worked great.
