access parameters on Windows

[loriab]

When the new D3 was picked up in QCEngine testing on Windows, it can't find the parameters file. Further below are traces from the conda-forge builds showing relative positioning on Linux and Windows. So I think this patch should fix up Windows, but it hasn't been tested.
