Description Bastiaan Veelo 2017-11-21 14:01:30 UTC 
When Visual Studio Community is the only version present on Windows 10, with the minimal set of options that satisfies the dmd installer (https://wiki.dlang.org/File:Visual_Studio_Installer.png) then dmd -m64 will fail to link:
LINK : fatal error LNK1104: cannot open file 'libucrt.lib'
Error: linker exited with status 1104

The problem goes away after changing UCRTVersion in C:\D\dmd2\windows\bin\sc.ini:

;UCRTVersion=winv6.3
UCRTVersion=10.0.10240.0


(Fresh dmd install.)

dmd-2.077.0

Use of the -m32mscoff option needs the same change under the [Environment32mscoff] section.
