Autodesk Moldflow Error 99998 Best _verified_ < 2024 >
If a beta version was previously installed, it can conflict with the current license. Uninstall it and clean up the registry.
Check if your material UDB file is corrupted. Try running the simulation with a "generic" material from the Moldflow library; if it works, the issue lies in your custom material data.
You can run this command for each product key (e.g., for 573O1 and 575O1) to ensure all license levels are correctly mapped.
Outdated or incompatible GPU drivers crashing the user interface or Synergy.

To verify the change, run the list command:
Ensure the , Level , and Server Name are correct. Apply changes and restart the software. Check Server Connectivity
: The workstation cannot bridge the hostname of the license server to its active IP address.
Resolving this requires verifying the handshake between the and the Moldflow Insight solver , configuring the Simulation Compute Manager (SCM) , and adjusting network license properties. Root Causes of Error 99998 If a beta version was previously installed, it
This is the most common fix for local workstation issues where the software isn't "pointing" to the right server. Close all Moldflow instances. Go to the Windows Start Menu and find Autodesk Moldflow Insight 202X License Configuration 202X Network License
Using separate servers for Synergy (UI) and Insight (Solver) can cause conflicts if the solver isn't manually pointed to its specific server.
Leftover temporary solve files blocking new processes.
Error 99998 is often a localized geometric singularity , not a global solver failure. Try running the simulation with a "generic" material
If the above methods do not resolve the error, try the following steps:
You will need to run a similar command for each product key (e.g., 573O1 , 574O1 , 575O1 ). After running these commands, you can verify the change by using the list command.
Error 99998 is fundamentally an unexpected termination error. It usually triggers when the Moldflow solver ( runflow.exe or related executables) attempts to read or write to a memory location it does not have permission to access, or when it encounters corrupted data. The most common root causes include:
Ensure it only contains the correct license server (e.g., @YOUR_SERVER_NAME ). Remove any invalid entries. Summary of Best Practices for Licensing To avoid Error 99998 in the future:
High aspect ratio elements (above 50:1 for Dual Domain or 100:1 for 3D) can cause the solver to "diverge" and crash. Aim for an average aspect ratio below 3:1.
