Hi Bruno,
Yes, all the source files are exactly where they should be. If any files were missing, the project could not possibly compile.
I tested this with a clean installation. All files are exactly where the installer put them, and the paths are exactly how the installer configured them.
And that brings us to another problem. If it's critical to have "Component Library Source" added to the Win32 library path, why is the WEB Core installer not doing this?
The only thing that the installer added to my Win32 library path is "WEB Core\RSXE12". Nothing else.
Update: I manually added "WEB Core\RSXE12\Component Library Source" to the Win32 library path. Then I closed Delphi and started it again. The structure errors are still there.
