installation directory with silent installer

Hi,
I have the following code:
!define MUI_PAGE_CUSTOMFUNCTION_PRE AbortIfUpdating
!define MUI_PAGE_CUSTOMFUNCTION_SHOW DirectoryPageShow
!insertmacro MUI_PAGE_DIRECTORY

But it seems that when silent the istaller doesn't get to DirectoryPageShow page. But it takes the istallation dir from somewhere. Where from?

Thanks.

InstallDir, InstallDirRegKey or $INSTDIR. See:
