Setting Class Libraries

Hi all, Quick question that I can't remember the hierarchy.

Situation:

Running a VFP App compiled in an EXE. This EXE has a VCX class library file compiled into it that the author used.

If I have a newer version of the VCX that performs some of the methods cleaner/faster than the one the author used, Can I simply place the newer VCX into the root of the application folder?

Will the newer VCX take precedence when the SET CLASSLIBRARY TO command runs in the EXE?

Thanks
