digitalmars.D.learn - DMD requirements (VC runtime version) where?

additional dependency on VS (for x64), and it is not documented, 
as far as I've been able to find, which versions.

So I just tried, and now the DMD Windows installer complains that 
it can't find any compatible versions of MSVC and the Windows 
SDK, after having installed 2017.

Is this documented somewhere that I've missed? Otherwise, would 
it be possible to add this information somewhere, namely which 
versions of what dependencies are required for what features?

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.

Thanks!

Nevertheless I think it would be good that the supported version 
of VS is documented on the website of DMD, just like it is on 
VisualD's. When the installer is updated, this document/webpage 
can be updated as well.

I don't immediately know how to find VS paths/exes and how to 
insert manually into sc.ini... But the VS extension manager is 
giving me some weird error message, so I'll just switch to 2015, 
even uninstall 2017.
