Do you use DllMain from http://dlang.org/dll.html#Cinterface? I guess 
so, if it runs on Vista/Win7.

What version of XP are you running? It might be a special version of 
ntdll.dll that is not supported. (I'll have to dig up supported versions 
from an older disk, though.)

Visual D is full of COM, but it does not use the default COM 
implementation, see https://d.puremagic.com/issues/show_bug.cgi?id=4092.
