How to install DMD 64bit on Windows? Is it just a case of downloading from here and it just works?

Or do I need Visual Studio installed?

Use the .exe installer and it will offer to download and install visual studio for you as part for its process.

I don't know if that feature has made it into a release yet. I don't think Vc2015 is supported yet either in a released version of DMD. I could be mistaken on both of these.

If you want to play it say just install VS2013 Community Edition then install DMD and everything should just work.

Sorry to ask this but could anyone please explain why Visual Studio is
required by DMD 64-bit? (I have been away far too long than I should
have)

Thanks

it's required for the standard C library (Digital Mars's one is 32 bit only) and to link COFF objects (Digital Mars linker is only for OMF objects, produced by default only by DMD32).
