If you have completed all the steps above and still receive Error 99998, gather the following for Autodesk Technical Support:
Error 99998 is intimidating because of its generic description, but it is rarely a true software bug. In over 80% of cases, the issue is environmental—either a clogged temp folder, a bad file path, or a permission conflict. By systematically working through the steps above, you can resolve the error and get your analysis running again without reinstalling the software.

In Autodesk Moldflow, Error 99998 is a general licensing failure that indicates the solver (Insight) cannot find or check out a valid license. While the error log might occasionally include terms like "full," it is rarely a disk space issue; instead, it typically means the license pool is full (all seats are in use) or the solver cannot reach the server. Common Causes & Fixes
License Seats are Full: If your organization has a limited number of seats, Error 99998 often occurs because all available licenses for Moldflow Insight are currently being used by other analyses or users.
Fix: Wait for other jobs to finish or check the License Manager (LMTools) to see who is using the seats.
Solver vs. UI Mismatch: You may have a license for Synergy (the user interface) but not for Insight (the solver). Error 99998 specifically triggers when the solver starts and fails to find its own separate license.
Incorrect License Configuration: The Simulation Compute Manager (SCM) or the solver might be looking at the wrong license server.
Fix: Run the License Configuration Tool (found in the Moldflow Insight folder in the Start menu) and re-enter your server hostname and license level (Standard, Premium, or Ultimate).
Network/Firewall Blocks: A firewall might be preventing the solver from communicating with the license server on ports 2080 or 27000-27009.
Expired License: Verify in your Autodesk Account that your subscription has not expired. If you suspect Disk Space ("Full")
If the error truly relates to a "full" drive rather than a full license pool:
Clear Temporary Files: Moldflow generates massive temporary files. Check the temporary directory defined in your Simulation Compute Manager settings and ensure that drive has at least 50–100GB of free space.
Reset Job Manager: Sometimes the database for the job manager becomes bloated or corrupted. You can follow the guide to reset the Simulation Job Manager database to clear stuck jobs. Solved: ** ERROR 99998 ** - Autodesk Community

Autodesk Moldflow Error 99998 occurs when the solver ( ) cannot access a valid license to start or complete an analysis
. This is primarily a licensing communication failure rather than a physical error with the model or mesh. Common Causes License Exhaustion:
All available seats for the required license level (Standard, Premium, or Ultimate) are currently in use by other users or background tasks. Missing Insight License: The license file includes (the UI) but lacks a seat for (the solver). Incorrect License Configuration:
The local software is not correctly pointed to the network license server, or the server information was entered incorrectly during setup. Server Connection Issues:
The license server is down, blocked by a firewall, or there is a significant clock time difference between the client machine and the server. Outdated Components:
The Autodesk License Manager (LMTools) or the License Configuration package is an outdated version that doesn't support the current software release. Primary Solutions Verify Server Status:
on the server and use the "Perform Status Inquiry" under the Server Status
tab to confirm that Insight solver seats (e.g., MFIB, MFIP, or MFIA) are listed and not all in use. Run License Configuration: On Windows, go to the Start Menu > Autodesk Moldflow Insight 202x License Configuration 202x Ensure the License Mode (Network), License Level Server Hostname are accurately defined. Clear Stuck Processes: Check the Windows Task Manager for rogue solver tasks like
. Ending these processes manually can often release a "hung" license. Update Environment Variables:
If the client is struggling to find the server, manually set the Windows environment variable ADSKFLEX_LICENSE_FILE 2080@YOUR_SERVER_IP Check Firewall Ports: Ensure that ports 27000-27009

Autodesk Moldflow Error 99998 generally indicates that the solver cannot access a required license. This can occur if all licenses are currently in use, the license has expired, or the software cannot communicate with the license server. Common Causes
License Availability: All AMI_STANDARD, PREMIUM, or ULTIMATE seats are occupied.
Server Communication: The license server is down, or firewall ports (e.g., TCP 44100/44200 for 2023) are blocked.
Configuration Issues: The licpath.lic file contains the wrong server name or IP address.
Installation Errors: An incorrect product key was used, or the License Configuration tool hasn't been run.
System Time: There is a significant time/date discrepancy between the client and the server. Step-by-Step Troubleshooting Check License Status Open LMTools on your server.
Navigate to the Server Status tab and click Perform Status Inquiry.
Verify if your solver licenses (MFIA, MFIB, or MFIP) are listed and if any seats are available. Clear Rogue Processes
If licenses appear "in use" but no jobs are running, open Task Manager.
End any instances of flow.exe, cool.exe, warp.exe, or mhb3d.exe that are at 0% CPU. Restart the adskscm (Simulation Compute Manager) service. Run License Configuration Utility
Go to Windows Start Menu > Autodesk Moldflow Insight 202x > License Configuration 202x.
Ensure the "Network License" is selected and the server hostname is correct (use port@server if using a custom port). Set Environment Variables
If requests are timing out, create a system variable named FLEXLM_TIMEOUT with a value of 10000000 (10 million) to give the server more time to respond.
Ensure ADSKFLEX_LICENSE_FILE is correctly set in your system variables. Verify Firewall Ports
Ensure the following TCP ports are open based on your version: 2023: 44100, 44200 2021: 43100, 43200 2017-2019: 43911, 42911, 43921

The dreaded Error 99998 in Autodesk Moldflow is a general solver failure that usually points to a breakdown in communication between the analysis engine and your computer’s hardware or temporary storage. When you see the "Full" designation attached to this error, it typically means the software has run out of space—either physically on your drive or within its allocated memory. 🛠️ Immediate Fixes for Error 99998 1. Clear Your Temporary Files
Moldflow creates massive scratch files during calculations. If your C: drive or designated Temporary Directory is full, the solver will crash instantly.
Locate your temporary folder (usually C:\Users\[Username]\AppData\Local\Temp). Delete all files beginning with s_ or mdt. Empty your Recycle Bin. 2. Check Disk Space and Project Location
Running simulations directly from a Network Drive or a Cloud Folder (like OneDrive or Dropbox) often triggers this error due to latency or "file in use" locks. Move your project (.sdy file) to a local SSD.
Ensure you have at least 2x the expected project size in free disk space. 3. Reset the Simulation Job Manager
Sometimes the communication link between the interface and the solver gets "stuck." Open the Simulation Job Manager. Cancel any "Hung" or "Failed" jobs.
Restart the service via the Windows Services menu (services.msc) by looking for Autodesk Simulation Job Manager. 🔍 Deep Dive: Why Does This Happen? Potential Cause What is happening? Mesh Density
Your mesh is too fine, creating more equations than your RAM can handle. Virtual Memory
Your Windows Page File is too small to handle the overflow from your RAM. Permissions
The solver doesn't have "Write" access to the temporary results folder. Antivirus
Your security software is scanning files while Moldflow tries to write to them. 💡 Pro Tips to Prevent Recurrence ⚙️ Optimize Your Hardware Settings
Increase Page File Size: Set your Windows Virtual Memory to at least 1.5x your physical RAM.
Update Graphics Drivers: Ensure your GPU drivers are certified for Autodesk products.
Clean Boot: Close memory-heavy applications like Chrome or Outlook before starting a long-sequence analysis. 📐 Refine Your Model
Use Symmetry: If your part is symmetrical, use symmetry constraints to cut the element count in half.
Check for Mesh Errors: Overlapping elements or high aspect ratios can cause the solver to "diverge," leading to a 99998 crash.
If you’ve cleared your drive and the error persists, I can help you dig deeper. To narrow it down, tell me: How many elements are in your current mesh?
Are you running a Fill+Pack or a more complex Cool+Fill+Pack+Warp sequence? How much Free Space is currently on your C: drive?
Knowing these details will help us determine if the issue is your model's complexity or your IT environment.
