Cannot run FlexTool on Microsoft server 12/2012

[e-zaline]

I have tried to install FlexTool in a Microsoft server 12/2012. The installation showed no error, but when running
python -m spinetoolbox, I get the following error:

(flextool) C:\Users\XXXX>python -m spinetoolbox
Traceback (most recent call last):
File "C:\Users\XXXX.conda\envs\flextool\lib\runpy.py", line 194, in _run_module_as_main

File "C:\Users\XXXX\Spine-Toolbox\spinetoolbox\main.py", line 28, in
from PySide6.QtGui import QFontDatabase
ImportError: DLL load failed while importing QtGui: The specified procedure could not be found.

Do you have any idea what could be the problem?

@soininen would you know a solution to this. I would guess that it's not really about Microsoft server as such, but that the installation has failed to get everything installed. There could e.g. be a policy against allowing unknown DLL files in the system.

Maybe adding the folder which contains the DLLs to the PATH environment variable would help? On my system, the folder would be C:\Users\XXX\AppData\Local\miniconda3\envs\flextool\Lib\site-packages\PySide6.

Thanks. Unfortunately it does not help.

Does it work if you try to install Toolbox using Python's virtual environment? You will need to have Python installed (not the Anaconda one) and follow the instructions in Installation from sources using Git.
