That usually happens if the DMD bin folder is searched first in the PATH 
variable (unfortunately the linker and other tools have the same name as 
the Microsoft programs).

You should verify that the VC folder is listed first in 
Tools->Options->Projects and Solutions->Visual D Settings->DMD 
Directories->x64->Executable Paths, i.e.

$(VCTOOLSINSTALLDIR)bin\HostX86\x86

should be listed before

$(DMDInstallDir)windows\bin
