Does Set Path and ClassLibs have the same effect at run time as during development?

I have a single EXE which will be used for each of the few countries where we have offices. The EXE is almost identical for each country, but not quite.

For each country, I have a single folder that contains files specific to that country. These will be the same file names as for other countries.

During development, I can simply use Set Path (for forms and PRGs) and Set ClassLib (for VCXs) to switch between countries.

Does this work the same at run time as well? I understand that I will have multiple files with the same name in my project, and multiple classes with the same name and am wondering, before trying this out, whether it will work.

Thanks in advance; it's been a while since I've been here.
