How can i get the "MSVCRT.DLL" from the "user path" instead of getting always from "system32" path?

Eventhough i placed the standard dlls like "gdi32.dll","kernel32.dll","msvcrt.dll" in the "user path", my EXE is getting all these from "system32" only. Is it not possible to modify these dlls anyway?

thanks in advance,
