Troubleshooting Autodesk Moldflow Error 99998: "Required license is not available"

The Error 99998 in Autodesk Moldflow typically indicates that the software’s solver is unable to secure a valid license to begin the analysis. This can occur even if the user interface (Synergy) is open and appears licensed, as the solver (Insight) requires its own handshake with the license server. 1. Check License Availability and "Rogue" Tasks

Before changing settings, verify that licenses are actually available.

License Server Status: Use the Autodesk Network License Manager to perform a "Status Inquiry." Confirm that AMI_STANDARD, AMI_PREMIUM, or AMI_ULTIMATE seats are free.

End Ghost Processes: Sometimes a previous analysis crashes but keeps the license "checked out." Open Windows Task Manager and end any lingering tasks for flow.exe, cool.exe, warp.exe, or mhb3d.exe to release stuck seats. 2. Verify License Configuration (Windows)

If seats are available but the error persists, the solver might be looking at the wrong server or using an incorrect product key.

Correct Server Info: Go to Windows Start > Autodesk Moldflow Insight 202x > License Configuration. Ensure the server name and license level (Standard, Premium, or Ultimate) match your purchase.

Sync System Time: Ensure the time, date, and time zone on both your workstation and the license server are identical. A discrepancy of more than a few minutes can cause a licensing timeout. 3. Linux-Specific Fixes

For users running Moldflow Insight on Linux, this error often stems from the Autodesk Licensing Service (ALS) configuration.

Update the mfclient.env File: Navigate to your solver installation folder and edit the mfclient.env file. Set the ADSK_SERVICE_ADDRESS to your server using the hostname:port format.

Check SCM Service: Ensure the Simulation Compute Manager (SCM) is running and configured correctly. You can check status using systemctl status adsklicensing. 4. Advanced Installation Issues

If the above steps fail, the issue may be rooted in the initial installation.

Product Key Mismatch: Confirm that you used the correct product keys during installation. Synergy (the UI) and Insight (the solver) use different keys.

Firewall & Network: For "Named User" licensing or cloud-based setups, ensure your firewall allows unrestricted access to api.autodesk.com on port 443. Common Cause Out of Licenses Wait for other jobs to finish or add more seats. Stuck Process Kill flow.exe in Task Manager. Wrong Server Name Update via the "License Configuration" tool. Network Block Open port 443 (Named User) or 27000-27009 (Network).
