No compiler is included natively with the Windows OS. Not even 
Microsoft's.

Or... you download the DMD installer which conveniently include 
it for you.

I don't understand this. You need DMD to build your EXE. I 
suppose you have this since your question is specifically about 
DMD. If that is the case you have the DLL you need.

True. In that case just distribute the DLL (taken from the DMD 
bin folder) alongside the HelloWorld EXE so that both reside in 
the same folder on the target computer. If you don't have 
administrative priveleges you cannot modify the PATH on the 
target computer either, so this is the only way. That is anyway 
quite standard under Windows - if you search for msvcr*.dll on 
any Windows machine you'll find lots of copies co-located with 
the EXEs that use them (using the version that came with the 
specific version of Visual Studio they were using to build the 
EXE - for example msvcr90.dll). These DLLs are simply the Visual 
Studio C/C++ Runtime distributed with Visual Studio.
