Device configuration tool not working in STM32CubeIDE v2.0.0

[mkx]

I've done a fresh install of STM32CubeIDE on my Win11 computer. (Version: 2.0.0 Build: 26820_20251114_1348 UTC). I installed CubeMX through Help > Install New Software and then tried to open an existing projects .ioc file. This did not work, I got the following error (log also attached)

The ioc file itself is fine. I can open it on other computers without a problem.

I tried installing CubeMX as a seperate program, which works fine. I assume its the CubeIDE plugin that has a problem

Hello @mkx 

As you can see here, CubeMX plug-in has been removed from the STM32CubeIDE.

CubeIDE no longer integrates the MX functionality - it's now only available in the separate, standalone application:

PS:

See this post (by @TDK ) on how to start an external editor from within the IDE.

Oh, I wasn't aware of that. Thanks for the quick answer.

Might be an idea to show this in the IDE in a a more user-friendly way. I was able to find and install the CubeMX plugin just fine, so it wasnt clear to me that this was a removed feature.
