app = App() raises exception

[vgelbgras]

Hi guys,

I am trying to use pymechanical on a virtual machine (the objective is to use the VM as runner for GH workflow running e2e tests).
When I try to get the App(), it raises an error.
Would you have some guidelines to debug this?

>>> from ansys.mechanical.core import App
>>> app = App()
CRITICAL -  -  logging - handle_exception - Uncaught exception

    self._app = _start_application(configuration, self._version, db_file)

I also try this

>>> from ansys.tools.path import find_mechanical
>>> find_mechanical(version=241)
('C:\\Program Files\\ANSYS Inc\\v241\\aisol\\bin\\winx64\\AnsysWBU.exe', 24.1)
>>> from ansys.mechanical.core import launch_mechanical
>>> mechanical = launch_mechanical()

Closing since this is moved to issues ( #780 ).
