6.2 Use a License File on the Client (Offline Fallback)

If you cannot resolve the network issue, borrow a license file:

  1. On the server, generate a stand-alone license file from Autodesk Account.
  2. Copy it to the client at C:\ProgramData\Autodesk\ADLM\ProductName\license.lic.
  3. Set environment variable ADSKFLEX_LICENSE_FILE to point to that local file path.
