🐞 Description of the bug

Hello!
I'm having difficulties trying to run the block model example. It seems i'm unable to load the CAD with mesh_util read.

https://prime.docs.pyansys.com/version/stable/examples/gallery_examples/gallery/00_lucid_file_IO.html#sphx-glr-examples-gallery-examples-gallery-00-lucid-file-io-py

I'm currently using py3.11.9 in a virtual environment, with ansys 2024R2 and py prime mesh 0.6.2. I'm on windows10.0.19045 pro.
I used the ProductConfig.exe script in the ansys files to configure CAD readers, and i can successfully read the example in SpaceClaim.

I tried investigating, and i launched the prime server without the launch_prime() function (using a cmd, calling the runPrime.bat) and i noticed the server correctly booting, but as soon as i run the example script on Python, trying to connect to the server and read the geometry; the server crashes saying "the DLL load failed while importing PyFM: the OS cannot execute %1". As soon as this error arises on the server prompt, i get the import CAD failed error in my python script.
I also encountered the same problem with some of my coworkers.
Do you have, by any chance, any idea where this could be coming from? Thank you very much

📝 Steps to reproduce

1. First in a cmd prompt: "%AWP_ROOT242%\meshing\Prime\runPrime.bat" server

which shows:
C:\Users\Guillaume>"%AWP_ROOT242%\meshing\Prime\runPrime.bat" server

Copyright 1987 - 2024 ANSYS,Inc. All Rights Reserved.
Starting Ansys Prime Server...
Server listening on : 127.0.0.1:50055

2. then i try running with python:
   import ansys.meshing.prime as prime

prime_client = prime.Client(ip="127.0.0.1", port=50055)
model = prime_client.model
mesh_util = prime.lucid.Mesh(model=model)

mesh_util.read(file_name="D:\MEC8370\PyPrimeMesh\test PyPrimeMesh 3\pyprime_block_import.scdoc")

print(model)

3. On the cmd prompt i used to launch the prime server, the error arises:
   C:\Users\Guillaume>"%AWP_ROOT242%\meshing\Prime\runPrime.bat" server

   (which is french for "the OS cannot execute %1)

4. The python scripts immediately crashes afterwards, with this error:

Hi @Guilladeb,

Have you reviewed the install logs to see if there was any issue with the ansys installation? You mention you have seen some coworkers experience the same issue? Have some not faced this issue? When you verified the file loaded correctly in SpaceClaim I am assuming this was on the same machine?
