I found this file and the value is 0 (maybe it's helpful)

However I followed this guide and I solved, now Ansys SpaceClaim ask me to login in less time and let me open SpaceClaim normally after the password validation: I used the already installed ansysls_client.exe without downloading the attached one (was too old). I added a new environment variable ANSYSLS_CLIENT_USE_ALT_HOSITD_METHOD=1  and reboot Please check if this solution it's valid for future version and is reliable. Thanks
