I'm not using any images for the buttons - they're the standard windows button for forms, etc
Code:
InstallButton:= TButton.Create(AutoRun);
with InstallButton do begin
Parent:= AutoRun;
Left := 20;
Top := 110;
Width := 150;
Height := 22;
Caption:= 'Install';
Cursor:= crHand;
OnClick := @InstallButtonClick;
end;
