System Workbench for STM32

Now it even won't compile anymore, because this error comes all the time, even after several build one after the other (unlike previously).

This is the detailed error:

Finished building: C:/STM32Cube_FW_F4_V1.16.0/Drivers/BSP/STM32F429I-Discovery/stm32f429i_discovery.c

How can I switch back to version V1.12 as you state, shall I install an old version of SW4STM32 or can I use this V1.12 compiler with SW4STM32 V2.0, and how to install (what plugin, etc...)?

Thanks.
