gpkit: Windows 10 (64bit) installation error, "no solver was given"

Perhaps there is an already resolved issue for this, but couldn’t find anything either here or in the readthedocs documentation. Did a fresh install of Anaconda (64 bit), created a virtual environment(should not have any effects), and installed all dependencies (see below for pip freeze). Mosek is properly installed as running mosek -f works fine, and the licence is properly working as running msktestlic proves. Gcc is also available in the command line through installation of mingw (64bit). Most gpkit tests pass, except a couple that seem to complain:

ValueError: No solver was given; perhaps gpkit was not properly installed, or found no solvers during the installation process

Going into gpkit\env\settings confirms the lack of solver as installed_solvers is blank. Any idea of what could be wrong?
