Gampang... kamu bisa pakai hex editor.
Disini kita coba pakai Resource Hacker.
Buka file iTurnOff (yang udah dipatch) dengan Resource Hacker.
Klik RCData trus buka TFRMMAIN
Klik di 0
Cari "14-days trial version"
object lblBuy: TLabel
Left = 10
Top = 458
Width = 117
Height = 13
Cursor = crHandPoint
Caption = '14-days trial version'
Font.Charset = ANSI_CHARSET
Font.Color = clBlue
Font.Height = -11
Font.Name = 'Tahoma'
Font.Style = [fsBold, fsUnderline]
ParentFont = False
Transparent = True
OnMouseDown = lblBuyMouseDown
OnMouseUp = lblBuyMouseUp
end
Hapus tulisan "14-days trial version" yang ada diCaption.
Klik menu Action trus Update All Resources.
