I've had this happen, too. I don't know for sure, but I think
it may be because the installers aren't prepared to do updates,
not on Windows, anyway.
My best success for updating has been to scrape D completely
off my drive (ie. uninstall DMC and DMD using Control Panel >
Programs and Features) then reinstall from scratch.
I only had DMD installed, but I uninstalled it and reinstalled to
no effect.
Removing Visual Studio 2017 did fix it though, which is both a
relief and to some dismay.
