I agree that this is the case. The closest thing I found to
documentation of this is
http://msdn.microsoft.com/en-us/library/ms235291.aspx under Deploying
Visual C++ library DLLs as private assemblies. It specifies that the
assembly be copied twice, once into the folder with the .exe and again
into the folder with the .dll.
I think the best option is to always install for everyone as
administrator on Vista.
