If the configuration is correct, check if the license server is actually serving the licenses. Open the License Manager Tool (LMTools) on the server.

is a critical licensing error in Autodesk Moldflow that occurs when the solver (Insight) fails to check out a valid license for the analysis. It is typically accompanied by a message stating that the required license for AMI_STANDARD AMI_PREMIUM AMI_ULTIMATE is unavailable or that all licenses are currently in use. Common Causes of Error 99998

To minimize the occurrence of Error 99998 and ensure a smooth Moldflow experience:

If you are facing a deadline, step through this rapid checklist: Action Item Target Issue Run Mesh Repair Wizard Mathematical geometry errors 2 Purge AppData\Local\Temp Corrupted cache locks 3 Increase Paging File size Out-of-memory crashes 4 Whitelist runflow.exe in Firewall Blocked local port communication 5 Reduce Solver Thread Count by 4 CPU instability / Thread collisions To help find the exact cause, let me know:

To resolve error 99998 in Autodesk Moldflow, try these steps:

Click , accept the confirmation pop-up, and restart your simulation. 2. Purge Ghost Processes from Task Manager

Run Mesh > Mesh Tools > Connectivity Assistant .

If the diagnostic test showed the error lies in the geometry:

Outdated or incompatible GPU drivers crashing the user interface or Synergy.

: In the same utility, verify the server name or IP address is correct. Use the format port@servername (e.g., 27000@yourserver ) if a custom port is required. 3. Connection & Network Issues

End these processes and restart the service (Simulation Compute Manager) via the Services tab. 4. Address OS-Specific Issues

Autodesk Moldflow Error 99998 is a roadblock to your simulation workflow, but it is rarely an insurmountable one. By understanding that the error is a license communication failure, you can move past frustration and take a systematic approach to solve it. Start with the easy fixes: restart the licensing service and run the License Configuration Utility. If the issue persists, use the manual command-line method on Windows or check for version conflicts on Linux.

. Ensure the license level (Standard, Premium, or Ultimate) matches your actual entitlement and that the server hostname is correct. Verify Server Communication:

Insufficient RAM or lack of virtual memory allocations.

For teams working over a corporate VPN or slow wide-area networks (WAN), latency often triggers premature timeouts. Forcing the system to wait longer usually clears the 99998 barrier.
