AJ,
The PLE thing is probably just a coincidence, but it was the only piece of information I could see in the manual as to why the toolset check box would be unavailable.
I'm sure when either Bob or Tony see your posting they will know immediately where the problem lies. I did notice on an earlier posting concerning Publishing, that the toolset option was not available either in the screen dump

I've just tried publishing both an old model and a new one I created, both times the include toolset option is available.
Are you publishing your model for use by others in the Vensim Model Reader, or in a VenApp or something like Sable. In the VenApp/Sable method you can always work around the non packaging of the toolset by distributing the toolset with the model, and then automatically loading it from within the Venapp or Sable, using the
SPECIAL>LOADTOOLSET|{toolname} command.
Sorry I can't be of more help at this point.
