We have a very large VFP application that has been using version 4.68 of wwipstuff.dll for a long time. We have to add some new functionality that requires a more recent version. Is it possible to have an application use two different versions of wwipstuff.dll? If not, are there certain things that you know of that will break or act differently if we don't change them?

No you can't use multiple copies of wwIPStuff.dll. A DLL can only be loaded into any given process once.

wwIPStuff.dll is matched to a set of library files in the Client Tools (or Web Connection), so you need to use the appropriate version of those libraries that goes with the wwIPStuff version.

While I don't update wwIPStuff.dll often there have been changes and trying to figure out what changes affect what version is not realistic.

You have to treat it as a matched set. You can try to update the libraries to the newer version which is possible but from 4.68 to 7.x is a long way so there are a lot of changes including moving from VCX files to PRG files for all libraries.
