Delphi-PRAXiS - Package TCOM

Hallo,
ich habe Windows 10 und Delphi XE5.
Habe ein altes Projekt (was schon lief) wieder in die Hand genommen.
Beim Compelieren bekomme ich nun folgende Fehlermeldung:
[dcc32 Fataler Fehler] E2202 Package 'TCom' wird benötigt, konnte aber nicht gefunden werden
Habe schon im Internet gesucht, aber nix gefunden.
Kann jemand helfen?
Ich benutze aber gar keine RS232 Schnittstelle.

Delphi-Quellcode:
