STCubeIDE wont start after a fresh install - should I rewind to an earlier version?

[Toneski]

Morning all,

I'm really having some issues getting the latest CubeIDE (1.18.1) to work.

This problem started when I was trying out some different processors for a new product (a CPU upgrade) - everytime I selected the new CPU and attempted to start a new project, I was told that it was missing an XML file and that no new project could be started without it.

After trying/retrying several times with searches for the XML file turning up nothing - I came to the conclusion that I needed a re-install of the tools as this would give me the XML file I needed for the new board.

I downloaded and installed the latest 1.18.1. Everytime I started CubeIDE, I would get a popup window after the splash screen  saying this or that log would hold the details of what was going wrong. Reading the log file showed that there was no swt-win32 in the java library path. The path listed in the log is pointing to a .DLL, which exists at the location given.

Assuming I had an old java install, I got and installed the latest, installed - rerun and the same issue.

I deleted the java install and rerun - same outcome.

I removed ALL ST software from my machine, re-installed, rerun - same outcome.

I have been through every combination - always with the same outcome.

I seem to be missing something - any ideas?

Should I re-wind to an earlier version? At least I could get on with some code for the project?

I'm out of ideas?

Regards,

Toneski.

This seems to be the error from the log file:-

Hi @Ghofrane GSOURI.

Thanks for your immediate reply.

I am running under Win7 64. Unfortunately, I cannot upgrade to something more recent due to other legacy tools that are required for the current hardware.

Regards,

Toneski.

Hello @Toneski 

Here are the host PC system requirements and supported operating systems for STM32CubeIDE version 1.18.0:
• Windows® 10 and 11, 64 bits (x64)
• Linux®: Ubuntu® LTS 22.04 and LTS 24.04, and Fedora® 40
• macOS® 14 (Sonoma), macOS® 15 (Sequoia)
Note: Windows is a trademark of the Microsoft group of companies.
Linux® is a registered trademark of Linus Torvalds.
Ubuntu® is a registered trademark of Canonical Ltd.
Fedora® is a trademark of Red Hat, Inc.
macOS® is a trademark of Apple Inc., registered in the U.S. and other countries and regions

So running STM32CubeIDE 1.18.0 on Windows 7 is not officially supported. However, you can consider using a virtual machine (VM) as a workaround to run STM32CubeIDE on a supported operating system while maintaining your legacy tools on Windows 7.
