Autodesk Moldflow Error 99998 is a critical licensing issue that occurs when the software's solver (Insight) cannot acquire a valid license from the server. The error message typically states: "Required license for AMI_STANDARD, AMI_PREMIUM or AMI_ULTIMATE is not available, or all licenses are currently in use". Core Causes This error often stems from one of three primary areas:

Availability: All available licenses are currently checked out by other users or active jobs.

Configuration: The client machine is pointing to the wrong license server, uses an incorrect port, or has an outdated Network License Manager (LMTools).

Connectivity: Firewalls are blocking communication, or the network timeout is reached before a license is granted. Top Troubleshooting Solutions

According to Autodesk Support, you should try these fixes in order: autodesk moldflow error 99998

Run the License Configuration UtilityClose Moldflow and search for "License Configuration 202X" in your Windows Start Menu. Ensure the License Mode, Level (Standard/Premium/Ultimate), and Server Name exactly match your subscription.

Increase License TimeoutIf your connection is slow (e.g., using a VPN), add a system environment variable named FLEXLM_TIMEOUT with a value of 10000000 (10 million) to give the server more time to respond.

Check Firewall PortsEnsure the specific ports for your Moldflow version are open for inbound and outbound traffic. For example: 2023: TCP 44100, 44200. 2021: TCP 43100, 43200. 2019 and older: TCP/UDP 43911, 42911, 43921.

Release "Stuck" LicensesOpen Task Manager on the server or client and look for rogue processes like flow.exe, cool.exe, or warp.exe. Ending these tasks can manually release a license that didn't check back in properly.

Verify Product KeysEnsure you used the correct product key during installation. Moldflow Synergy (the UI) and Insight (the solver) require separate keys, which change with every version. Expert Review Summary Commonality

Very High – It is one of the most frequent licensing hurdles in Moldflow environments. Complexity

Moderate – Usually solvable via configuration, but complex for Linux or distributed solve setups. Recommendation

Always check the Autodesk License Parser first to confirm your .lic file actually contains the Insight solver feature.

Title: Troubleshooting Autodesk Moldflow Error 99998: Causes and Solutions

Introduction

Autodesk Moldflow is a powerful simulation tool for plastic injection molding, but like any complex software, it can occasionally throw cryptic errors. One such frustrating issue is Error 99998 , often accompanied by a message indicating a "general solver failure" or "unexpected termination." This error typically appears during the analysis phase, halting your simulation and disrupting project timelines.

This article outlines the common causes of Error 99998 in Moldflow (both Insight and Synergy) and provides step-by-step solutions to resolve it.

What Does Error 99998 Mean?

Error 99998 is a generic solver exit code. Unlike errors 1000–5000, which point to specific modeling or material issues, 99998 signals that the solver encountered an unhandled exception—often due to system resources, file corruption, or mesh anomalies. It can occur in Fill, Pack, Warp, or Cool analyses.

Common Causes

Step-by-Step Troubleshooting

As a last resort, uninstall Moldflow and then reinstall it. Make sure to also clean out any residual files and registry entries if you're comfortable doing so. Error 99998 is a non-specific failure code usually

If you're still encountering issues after trying these steps, providing more details about your specific situation (such as the version of Moldflow you're using, your system specs, and any recent changes you've made) could help in pinpointing a more precise solution.

In Autodesk Moldflow, Error 99998 is a licensing error indicating that the required solver license (such as AMI_STANDARD, AMI_PREMIUM, or AMI_ULTIMATE) is not available or cannot be accessed. Common Causes

License Configuration Not Set: The software hasn't been told where to find the license or which level to use.

Missing or Expired License: The Insight solver license may have expired or is not present in the license file.

Incompatibility: Installing a license level update (e.g., Premium) when you have an Ultimate license.

Server Issues: The license server hostname is incorrect, or the Simulation Compute Manager (SCM) cannot communicate with the server. Solutions for Windows Run License Configuration: Close all instances of Moldflow.

Open the Windows Start Menu > Autodesk Moldflow Insight 202X > License Configuration 202X.

Verify the License Mode (e.g., Network) and License Level (Standard, Premium, or Ultimate) match your subscription.

Ensure the License Server hostname is correct and click Apply. Verify Server Status: Use the LMTools Utility on your license server.

Go to the Server Status tab and click Perform Status Inquiry.

Confirm that the solver feature codes (e.g., MFIB, MFIP, or MFIA) are listed and not expired. Update Licensing Service:

In some cases, the Autodesk Desktop Licensing Service may be corrupted or outdated and requires a reinstall. Solutions for Linux

Install License Configuration Package: For 2021 or newer releases, ensure the license configuration package is installed separately, as it is no longer part of the standard solver installation.

Check Environment Variables: Verify that ADSK_SERVICE_ADDRESS is pointing to the correct Autodesk Licensing Service (ALS) hostname and port (e.g., host:port).

Are you using a network license or Named User licensing, and which version of Moldflow are you currently running? Solved: ** ERROR 99998 ** - Autodesk Community

Error 99998 in Autodesk Moldflow indicates that the required solver license (such as AMI_STANDARD, AMI_PREMIUM, or AMI_ULTIMATE) is not available, or all licenses are currently in use. This error usually occurs when you try to start a simulation and the solver cannot communicate with the license server. Common Causes & Solutions

License Configuration is Missing or Incorrect: The most frequent cause is that the "License Configuration" utility has not been run or is pointing to the wrong server. Step-by-Step Troubleshooting As a last resort

Solution: Close Moldflow. From the Windows Start menu, navigate to the Autodesk Moldflow Insight/Adviser 202X folder and run License Configuration 202X. Ensure the license level (Standard/Premium/Ultimate) and the server name or IP address are correct.

Stuck Solver Processes: Sometimes a previous analysis doesn't close properly, "holding" the license hostage.

Solution: Open Task Manager and look for rogue processes like flow.exe, cool.exe, warp.exe, or mhb3d.exe. If any are at 0% CPU but still running, end them to release the license.

License Server Timeout: If the server takes too long to respond (common over VPNs), the request fails.

Solution: Add a system environment variable named FLEXLM_TIMEOUT with a value of 10000000 (10 million) to give the software more time to reach the server.

Simulation Compute Manager (SCM) Issues: For versions 2021 and newer, the SCM handles job distribution and licensing.

Solution: Check that the Autodesk Simulation Compute Manager service is running in Windows Services. If it is stuck, restart it and try the analysis again.

Firewall Blocks: Communication ports for Moldflow (which vary by release) might be blocked.

Solution: Verify that the necessary inbound and outbound firewall ports for your specific Moldflow version are open on both the client and server.

Title: The Midnight Case of Error 99998

Setting: The Product Development Lab, 11:47 PM. A launch deadline looms in 72 hours.

The Character: Sarah, a senior plastics engineer. She has just finished a complex 3D mesh on a thin-walled electronic enclosure. She clicks “Analyze Now.” The progress bar crawls to 32%, then freezes. A red dialog box appears:

“Error 99998: Solution did not converge. Unable to meet fill tolerance.”

Her stomach drops. Not a crash. Not a memory error. Convergence failure.

Running Moldflow studies from a mapped network drive (e.g., Z:\Projects\) is risky. A brief network drop or latency spike during the initial solver handshake will cause the solver to abort with Error 99998.

A tier-one automotive supplier was running a warp analysis on a 2.5 million element 3D dashboard bezel (ABS/PC). Every run failed at 87% of the "Pack" stage with Error 99998. The mesh statistics were excellent (avg aspect ratio 5.2, no negative Jacobians).

Diagnosis: The IT department had recently deployed Symantec Endpoint Protection. The log showed Symantec was scanning C:\Users\moldflow_user\AppData\Local\Temp\moldflow_4567.mfr exactly at the moment of failure.

Solution: The engineering workstation was moved to an antivirus exclusion group for all .mfr, .m3r, and .mda file types. The analysis completed successfully in 4 hours, and warpage predictions matched physical scan data within 0.3 mm.
