I've wanted to use OpenStudio 2.9.1 for a project for my thesis. However, whenever I try to set a weather file, I get a warning "Failed To Set Weather File To [filepath]". This happens with the weather files I wanted to use for my project, the weather files bundled in my EnergyPlus installation, and weather files downloaded from energyplus.net/weather, like for example this one.
This is a fresh installation of OpenStudio 2.9.1, with nothing done to it beforehand, as this was the first thing I tried. The only clue I found by searching was that this can be caused by special characters in the path or filename. However, none of those are in my file names, and I've tried moving and renaming the weather file to no avail. I would be happy to any clue as to what I'm doing wrong.
This is on Windows 10, if that matters.
