We got the same message in the following setup.
Os:- WIN2K
Application setup C++, MFC.

Problem Description:-
In a dialog based mfc application which loads two mfc regular dlls,
(Say DLL1 and DLL2 where DLL2 uses XFS library
msxfs.lib,xfs_conf.lib,xfs_supp.lib), the message
"invalid virtual base addr.; GetLastError 487"
pops on executing the application.

Project settings Details:-
In 'Object/library module' of project settings,the order of
libs are as Lib1, Lib2 (Lib1 for DLL1 & Lib2 for DLL2).

By changing the order of libs in the project settings,
that is loading 'Lib2' before 'Lib1', this problem is resolved.
