Hi Remy,
Thanks for your kind answer, but I still can't get it to work.

This is what I'm exactly doing in the package (named MyPackage.bpl):

namespace Mypackage

{
  void __fastcall PACKAGE Register()
  {
 RegisterClass(__classid(TForm1));
  }
}

In the main app (Build with runtime packages checked), I do this:

 try {
  int bpl=LoadPackage("Mypackage.bpl");
  if (!bpl) { ShowMessage("error"); return; }
  TMetaClass* p=GetClass("TForm1");
  if (!p) { ShowMessage("No class"); return; }
  UnloadPackage(bpl);

 } catch (...) {
     ShowMessage("error");
 }

I always get a "No class" error, because the GetClass() can't find the 
TForm1 class.
Am I doing anything wrong?

Thanks very much again,
Pere
