uVision Peripherals System Viewer shows empty since upgrading

I am using Keil uVision V5.37 with STM32F4xx MCU.  I have recently upgraded my project to use the latest versions of CMIS, Middleware, STM32F4xx DFP packs, as well as upgrading from V5 compiler to V6.18.

Since then, if I select Peripherals->System Viewer in uVision then the list is empty - no peripherals are listed.

Is there a solution for this?
