Description of the bug

Costas Vogiatzis @ Honeywell receives the following error when attempting to read an rst file: Attempting to use the standalone DPF I get the error below. It seems that it’s looking for files that were not part of the DPF distribution:

Hello @agrishin,

For Ansys 2024 R1, you need at least ansys-dpf-post==0.6.0 (with ansys-dpf-core==0.10.1), which is only available for Python 3.9 and above.

The customer's response:

Perhaps not surprisingly the dpf version is not the problem. I have updated to the latest modules and switched to python 3.11 but the problem persists.

Hi @agrishin,

the last error states: NotADirectoryError: DPF directory not found at C:\Users\e092220\Documents\TEMP\ansys_dpf_server_win_v2024.1.pre0\ansys\aisol\bin\winx64

which makes it impossible to start a DPF server.

Can the customer verify that the folder does indeed not exist?
