Dear Javier,
Please be sure you are using the latest updated version of SAM 2015.6.30. ISCC was not part of the original release, but was added as a revision to the original release.
I would recommend downloading the current version from the Downloads page, then uninstall your current installation of SAM 2015.6.30 and install the latest version. SAM should automatically offer to update, so you could instead update your version by allowing it to update when you start the software.
Best regards,
Paul.
