Issue:

After installing an Autodesk 2020 or newer versions and modifying the licpath.lic file to use a non-standard port or a new server name, the Licpath.lic file is being automatically changed back to the default port, server name or IP Address after restarting the Autodesk Desktop Licensing Service or the machine.
Is there any way stopping the auto-update in the file ?

Causes:

Solution:

There is no way stopping the auto update as it is pulled information from registry key and environment value ADSKFLEX_LICENSE_FILE. If a 2019 or prior products working on a machine, the 2020 and higher products would use the same server information in ADSKFLEX_LICENSE_FILE.
Update Registry key and Environment value to use the same port, server name or IP Address in order to prevent resetting Licpath.lic file into the previous configuration.
