Same problem as I have. After installation of SW4STM32 and F4Discovery-FW everything was fine. But with the installation of CubeHAL-FW the problem started. The Discovery-FW (StdPeriph lib) is consequently ignored. I’ve checked the firmware installation properties and tried to add the location explicitely on first position. But it didn’t solve the problem.
I made a screenshot wallpaper showing everything. It is attached as PDF.
The error message might come from the attempt to overwrite the existing installation. But why is it then a loss of connection?
Maybe there is something with the “repository sharing helper”.
