In general, it possible only if You compile & link Your project against specific version of CRT libraries. Given version of VS has support for concrete version of these libs:
VS 2005 => msvcrt8
VS 2008 => msvcrt9
Std lib are linked against via #pragma comment(lib, "libcXXX.lib")
or #pragma comment(lib, "msvcXXX.lib")
depending on Your project configuration (look at afx.h)
There is no dependency definition for CruntimeLib in VCPROJ, so You have nothing to change in here.
If you get complete tree of required libs/dlls/headers in older version (8.0) for a concrete platform (example.: Win32 or PocketPC 2003, etc.)
You will need to change paths for a given platform in:
Tools / Options / Project and Solutions / VC++ Directories
(!!!ATTENTION backup Your config before via export operation from menu)
