STMCubeIDE not opening ioc in MX mode

My STMCubeIDE is not opening the ioc files or creating STM32 projects, it is acting like the ioc files are text files, not using the STMCubeMX mode to open them. I'd already tried reinstalling the STMCubeIDE a few times, in the C folder and in other disk, tried checking for updates, confirming the installed plugins, deleting the folder after uninstalling the program and many other ways to fix it. Can someone help me?? Please

STM32CubeIDE 2.0 no longer has a bundled STM32CubeMX. You will need to download this and use it as a standalone application.

Hello @pimenta1004 ,

 

In order to open successfully the Ioc.File on STM32CubeIDE 2.0, you need to open it by default on the project folder with MicroXplorer for STM32Cube application.
