I am trying to recompile old Delphi program from 2011 which uses external bpl packages. They are named as SentrolBase150.bpl and so on but when I am trying to import those packages I am getting an error message saying rtl150.bpl not found.
I looked to Delphi install folder and found rtl240.bpl there (I have installed RAD Studio 10.1 version).
Is there way to use those old existing bpl packages or do I have to rebuild package from scratch? I have full source code but I don't know (yet) how to build it.
Or have I misunderstood something. I haven't done Delphi programming since 90s.
