stm32cubeMX is not starting

modecs · ‎2026-01-13

Hello,

I was using STM32CubeMX, but starting two days ago, when I launch the program, only the splash screen appears and the STM32CubeMX does not proceed any further.

1. I have tried deleting the program, restarting the computer, reinstalling it, and running it again.
2. Adding a new user is not possible; the user creation permission is restricted to the company's IT administrator.

I would appreciate any suggestions on additional steps I could take to resolve this issue.

You should at least note the OS you are working with, and the CubeMX version.

Under Unix/Linux, starting an application from commandline usually yields the error messages you are looking for. Not sure about Windows here ...
Another option is to locate the CubeMX executable, and look for log files created for each start.

Additionally, the same issue occurs with the ST MCU Finder program: it also fails to start. For both applications, the splash screen appears, but the programs do not continue launching; in the Task Manager -> background‑process list they are shown as “OpenJDK Platform binary.”

Because it's a Java application.

While you can try to run it manually from console to review error messages, they all create a quite extensive logfile.
I don't use either, so I can't point you to explicit path names.

Hello @modecs

Please close all STM32Cube software ,then go to C:\Users\XXX and delete the following folders/files:
\.stm32cubemx, \.stmcufinder, and \.stmcube.

After that, restart STM32CubeMX and check if the issue is resolved.
