Version information for the problematic install:

Hugo Static Site Generator v0.18 BuildDate: 2016-12-28T10:58:46-05:00

The same site works with Hugo 0.17 installed through Chocolatey on the same machine, with the following version info:

Hugo Static Site Generator v0.17 BuildDate: 2016-10-07T15:45:24-04:00

the site also works with Hugo 0.18 on a 64-bit Ubuntu machine. Let me know what other info you need. We are using version 0.17 for now, so we are operable, but I thought you might like to know.
