Missing firmware packages - can't create a project

[KOlsz.1]

Fresh installation, when I try to create a STM32 project a zip file with firmware is downloaded and unpacked, but I still get this error message:

"Code generation could not be done because necessary firmware package is missing. Not able to complete STM32Cube project."

I tried to download and unzip these files manually with no luck.

I have this issue on my both PCs with windows 10. Also the same thing happens regardless if I try to create a project for my Nucleo F030R8 or Nucleo L053R8.

STMCubeIDE > Help > Manage Embedded Software Packages shows the installed packages and offers options to add/remove new ones. Try that.

It didn't help. Creating a new project generates .ioc file but doesn't generate any code. I'm still getting this error message.

Also when I right-click on the .ioc file the option "generate code" is disabled
