When compiling for Windows and including the Runtime DLLs, "should" I be able to place them into the Libs folder instead of leaving them at the app level in the resulting build folder?
No you can't
@Tim P No you can't
Well, that explains the errors :S
What a messy, messy, mess.
(I should clarify - "user's errors". A user didn't like it, so they tried moving them into the Libs folder next to the app.
