What's up with the three DLLs?  Shouldn't just one suffice?  And 
what's up with %1 ?


Strangely enough, I've got a working Visual Studio project with 
the same FreeType load command that works fine?  It uses

I tried just copying and pasting this .dll into the same folder 
as the failing .exe
but it still returns the above error.

Thanks.

Some shared libraries can be found in the wild using different 
formats for the file names. In the cases where I'm aware of it, 
as in this one, I've implemented the loaders to attempt to load 
them all. If any one of them is present, the load will be 
successful. If not, they are all listed in the exception message.

 And what's up with %1 ?

This is an error message from the operating system. The 'not a 
valid Win32 application' message usually arises when you try when 
you have an architecture mismatch between the shared library you 
are trying to load and your application. That is, one of them is 
32-bit and the other 64-bit. My guess is you are compiling using 
the default DMD toolchain, which is 32-bit, but your FreeType DLL 
is 64-bit. Could that be your problem?
