Hello Colin,
I installed VisTrails and SAHM from the link on a new computer and uninstalled before reinstalling on another. I think that was already the most up-to-date version so I just broke it. It now asks me to update python (don't know how to do that) and it will start a pipeline and just stop without throwing errors. It's on "Template Layer" which is maybe the first thing it does anyway. 'Template Layer' is red, everything else is blue, and it seems to be stalled.
Could python be the problem? I seem to have R-3.2.0 loaded, Maxent is downloaded. I just get a "IPython.qt.console.rich_ipython_widget" failed. It then tries to install bundle, says Requirement already satisfied, but asks me to consider upgrading via the 'python -m pip install --upgrade pip' command (but where, how?)
