Specifications

cate-2.0.0.dev16, Windows 10

[hans-permana]

this was caused by gdal and fiona relying on vs2015_runtime 14 and in new Miniconda, v15 is automatically installed.

A workaround was done in this commit CCI-Tools/cate-conda@2599d8e by adding vs2015_runtime version 14 specifically in cate-cli meta.yml. This seems to fix the problem.
