The Autodesk Network License Not Available Error [-8.544.0] typically occurs during software launch when the client machine cannot communicate effectively with the license server. This is often due to an incorrect license type assignment, server-side restrictions, or corrupted registry values. Common Causes
Incorrect License Type: The user is assigned a different license type (e.g., Single-user) in their Autodesk Account but the software is trying to launch as a Multi-user/Network license.
Server Communication Issues: The license server may be down, all licenses are currently in use, or the license has expired.
Options File Restrictions: An options file (adskflex.opt) on the server may be explicitly excluding the user or computer from accessing the license.
Incompatible Versions: A mismatch between the client’s Autodesk Licensing Service and the server’s Network License Manager (LMTOOLS) version (typically requires LMTOOLS v11.18 or higher).
Registry Errors: Invalid pathways or values in the Windows Registry for the FLEXlm License Manager. Recommended Solutions 1. Verify and Reset License Type
Confirm the assigned license type in your Autodesk Account. If it is "Sign In" (Single-user) but the error persists, you must reset the local license type:
Use the Autodesk Licensing Support Tool to change the method to "User" or "Sign In".
Alternatively, reset it manually by deleting the LoginState.xml file located in %LocalAppData%\Autodesk\Web Services\. 2. Check Server Options File If your organization uses an options file to manage usage:
Ensure the specific user or computer name is included in the INCLUDE list for that product. Check that they are not listed under an EXCLUDE command. 3. Clear Invalid Registry Values
A common fix involves removing old or incorrect license server paths from the registry:
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\FLEXlm License Manager. Delete the value ADSKFLEX_LICENSE_FILE.
Restart the product and enter the correct license server name when prompted. 4. Update Licensing Components
Ensure both the client and server are running the latest versions to avoid compatibility errors:
Client: Download and install the latest Autodesk Desktop Licensing Service from the Autodesk Support site. Server: Upgrade LMTOOLS to version 11.18 or higher. 5. Firewall and Port Configuration
Verify that essential ports (typically 27000-27009 and 2080) are not blocked by the Windows Firewall or any antivirus software on either the client or the server.
