The paths have changed in VS 2017 and the DMD installer hasn't 
been modified to pick them up yet. You can edit the paths in 
sc.ini manually, or you can install the MS Build Tools 2015. You 
can do that via the download link [1], or by running the VS 2017 
installer again and:

* click 'Update' if you see it, otherwise click 'Modify'
* go to the 'Individual Components' tab
* scroll down to 'Compilers, build tools and runtimes'
* check VC++ 2015.3 v140 toolset (x86, x64)

I actually haven't tested if the DMD installer recognizes the 
2015 toolset you get through the 2017 installer -- I'm assuming 
the paths will be the same as they are with the MS Build Tools 
download, but they may well be different. Regardless, editing 
sc.ini manually is the better option if you don't need or want 
the 2015 build tools.
