Il suffit d'éditer le fichier LICPATH.lic, puis remplacer l'ancien nom dns du serveur de licence avec le nouveau

The LICPATH.LIC file for 2017 & 2018 & 2019 Version products are located in  C:\ProgramData\Autodesk\CLM\LGS\Product-Key_201x.0.0.F.

For example for AutoCAD 2019 the path to LICPATH.lic file would be C:\ProgramData\Autodesk\CLM\LGS\001K1_2019.0.0.F\LICPATH.lic.

Note: If you have another Autodesk software installed on your system that is pointing to the same license server as your Autodesk 2017 product, then LICPATH.lic file may not be created as the license server information would be retrieved from the system registry [HKEY_CURRENT_USER\Software\FLEXlm License Manager >  ADSKFLEX_LICENSE_FILE ]
