Some good tools to help you hunt down problems like this:

Depends (http://www.dependencywalker.com/) - Run against a EXE to see
what normal DLL's it depends on.
FusLogViewer (http://blogs.msdn.com/junfeng/archive/2004/02/14/72912.aspx)
Lets you specifically watch .NET exes as they execute to see what and
where they are trying to load.
