Last month about 19% of our downloads were for the 32-bit installer and 7% were for the PortableApps package. The percentage of 32-bit installs is steadily decreasing over time, but we're not close to zero yet. As far as library compatibility goes, according to https://docs.microsoft.com/en-us/cpp/porting/binary-compat-2015-2017 we *should* be able to build using Visual C++ 2017 and use libraries compiled with Visual C++ 2015. I did a test build here using Visual C++ 2017 and the "msvc2015" Qt component here and it seems to work OK. Dependencies[1] reports that it's using msvcp140.dll and vcruntime140.dll. I went ahead and switched the Windows master and PD builders over. The 64-bit builders are now using the Qt 5.9.4 "msvc2017 64-bit" component and the 32-bit builder is using the "msvc2015 32-bit" component. If that doesn't work we can try the "MinGW 5.3.0 32-bit" component. We can also switch back to Visual C++ 2015 if needed.
