У меня Delphi 2005 Architect Edition Trial-версия. Пробовал ставить Update 1 и Update 2 — ни один не пошел — матерится: "The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch."
Это что же они на trial не ставяться что ли вообще?
