The [Microsoft Reciprocal License](http://wixtoolset.org/about/license/) (here taken from the WIX toolset I use) has the following sentence:

> 
> For any file you distribute that contains code from the software (in source code or binary format), you must provide recipients the source code to that file along with a copy of this license
> 
> 
> 

Does that mean I have to provide the source code even if I only use the unmodified (original) DLL in binary format? Note that this unmodified DLL contains code from the software, although it was not compiled by me.

What does *provide* mean? Shall I provide 11 MB of source code as part of my application (install the source on hard disk) or can I provide it as an extra download as well?
