Hello,
The installation of S32 Design Studio requires that the user's account on Windows is a member of the administrator's group. If your account does not meet this requirement, then perhaps you can use the Run as Administrator option. Another possibility, you could try to enable Windows 7 compatibility mode. Or contact your IT department for assistance.
Installing the Synopsis VDK eclipse plug-in isn't required to use S32DS. In general, this is used for development work which occurs prior to the availability of actual hardware (NXP devices, evaluation boards, etc.). I ask you again, do you know that you need this plug-in, or are you only requesting it because of the note displayed in the installer?
Best Regards,
Mike
