I'm losing hair for three days now over this problem. Here's the layout of it:

I have to have a replaceable module, which would simply be a bunch of files (vcx, prg, dbf) in a subfolder, so that any updates can be done independently from the main exe. The plan is to actually have the users get the latest from the web, just unzip to this folder (all can be automated, just like other similar cases), but...

The parent classes of the classes in those classlibs are inside the exe. 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.

How do I tell it to find the vcx inside the exe?
