Ok, I see how you get to 32/64 msvc2015 but only 64 for msvc2017. :[ That's from the online installer.
I presume I won't be able to build what I want within the hour limit per job, nor would that be kind to the service even if it did fit in the hour. My local install is 3.8gb which would require the premium $100/month fee which I won't be paying for this open source project. :] I guess other than you being willing to build msvc2017-32 for me I'll go and build it myself and make an installer available for download somewhere and download/install each time (and hope that doesn't take too long).
Let me know where you stand on this, thanks for the consideration.
Hmm... so apparently 2017/2015 are binary compatible so I can do my build for Python 3.7 (built with msvc2017) with msvc2015 instead and it still seems to work. I'd still be interested in an msvc2017 Qt 5.11 to avoid playing games, but if I don't get it I won't be stuck.
