In general terms, you want to put any version-sensitive .DLL in the directory that the executable lives in, based on the default search path used by Win32 to locate a .DLL file. The directory containing the executable is searched by default before the shared Windows directory paths. FWIW, the default search order used by the Win32 file system to resolve files (it usesthe SearchPath() API call) is:

(1) The directory where the application executable was loaded
(2) The current directory
(3) The Windows system directory (returned by the GetSystemDirectory() API call)
(4) The Windows directory (returned by the GetWindowsDirectory() API call)
(5) The directories listed in the PATH environment variable

OLE components are a separate problem; if the IDispatch interface is used, whoever registers last wins, regardless of where the OLE component can be found.
