Hello,
I have checked it and the S32K116_EVB_JumpStart_Firmware uses SDK v 1.8.7 which can be downloaded on this link: S32 Design Studio for Arm® 2018.R1 Update 2 - S32K118 Bare Metal Device Support(REV UP2)
After that, you should be able to install software by offline installation:

If you have questions related to S32K1xx devices and SDK I recommend you to ask directly in the S32 SDK community:
I hope it helps.
Best Regards,
Diana
