JRE for MCSDK 5.4.8 MotorWorkbench?

[SKled.1]

I installed MCSDK 5.4.8 and CubeMX 5.2, which runs, so, if it uses Java, a suitable version must be installed.

But when I try to Generate from a MotorWorkbench project, it gives me this error:

Generation process failed. The embedded JRE was not found. Please check the correctness of installation.

How do I fix this problem? [I assume I can't just install any JRE willy nilly]
