GUI SFX module -sp switch passes parameters to setup application only if no other parameters were specified in "Setup" command in SFX script. So "Setup" command has a higher priority than -sp. Regardless of -sp presence, setup application can read the full SFX command line from sfxcmd environment variable. 3. "Save current settings" button in "Advanced SFX options" dialog is now available only when converting an existing archive to SFX. Options saved with this button are applied only to convert to SFX operation. If you create or update SFX archive, only SFX options stored in default compression profile are used. Options saved in "Advanced SFX options" dialog are ignored for these operations.
