stm32CubeMX can not install X-CUBE-SPN1 package

[TMerk]

I have installed the newest version from STM32Cube (5.0.1) and want to use the X-Cube-SPN1 software expansion. The expansion I have downloaded from st.com, so I want install it from local as a zip-file. (I use the menu Help/manage embedded software...)

But the STM32Cube gives an error message:

This package version is not managed on this version of stm32cubemx.

What can I do?
