It's possible your installation is missing a required update to the P&E drivers. Please go to Help -> Install New Software and then select 'PEMicro - http://www.pemicro.com/eclipse/updates' to check that you have the latest updates and get them installed, next check that you have the S32K3 Development Package, and then try the S32K3 RTD install again.
Best Regards,
