Hello. I’ve read an old closed thrad saying that there was an issue on virtual machines with FME 2023/2024.

At our side we did not experience any issue on virtual machines with FME 2022-2024.

But we just installed FME 2025.1.1 and get this issue “SetThreadDescription entry point not found in Qt6Core_fme.dll.

Any idea? Stille the same issue?

(It is on Windows 10 Pro)

Hi ​@jerome.ray thanks for your question. I haven’t seen this issue come up again, I think it might be best to submit a support ticket with additional details so that our team can look into this further. 

You can submit a ticket here, please provide the following (if available):
- Details about the environment used (e.g. platform and OS version, virtual environment, any other dependencies, etc.)
- Any relevant log files (e.g. translation logs, crash logs, system logs, etc.)
- Any relevant screenshots (e.g. errors, configurations, etc.)

Not directly related but somewhat.

We recently had a customer with Windows Server 2016 using FME Flow 2025.1.  They could not start the Engines Service (this is a known issue).  It appeared the Engine service was not able to load fme.dll and would crash and restart.   

I’m surprised that Windows 10 is supported and is allowing FME Form to run it’s FME.exe (Engine). It’s clear I do not fully understand the problem.  

  
In case someone finds an issue with Windows 10 Pro and FME Flow 2025.x… we’d like to hear.

We say in our Tech Specs (linked below) that it is supported… but tread carefully.

Upgrading the OS may be required.
