The relative paths to these parent classes are pointing to those inside the main exe, e.g. if there's a classlib called libs\main\blabla.vcx, its subclass in the addon\subbla.vcx has ..\libs\blabla.vcx in its classloc memo. But it won't find it - it says "libs\main\blabla.vcx does not exist". I even tried removing path from classloc in subbla.vcx, tried explicitly opening the classlib inside the exe, tried creating an object based on a class from it, nothing works.

Maybe it is a naive proposition but why not to include the parent class VCXs into the module that you use separately from the main EXE?
