Use the to automatically fix overlapping elements, free edges, and non-manifold nodes.

If you manually unpack thin clients, the core solver will return Error 99998 unless the configuration framework is built. Run the terminal shell utility bundled inside your source installation bundle:

: The software is pointing to the wrong license server, or the "License Configuration" utility hasn't been set up on the local machine. Mismatched Software Versions

The infamous Autodesk Moldflow error 99998!

Contact Autodesk Support with your solver log file ( *.mfl ), Windows Event log, and a copy of your study. Mention that you have already excluded path and antivirus issues to accelerate the support ticket.

Uninstall the from the Control Panel.

: The license for the specific solver (e.g., MFIB, MFIP, or MFIA) is missing from the server or has expired. Incorrect License Configuration

Most instances of Error 99998 stem from three primary categories: mesh quality, hardware limitations, or software/license conflicts. 1. Mesh Defects and Geometric Issues

Select in the Advanced properties window. Under System Variables , click New .

Autodesk support can use these to identify if the error is due to a specific graphics driver conflict or a rare file system filter driver issue.

Track . If memory utilization reaches 90-95%, your model is too large for your hardware. You will need to increase system RAM, optimize the mesh to reduce element count, or utilize aggressive mesh aggregation.

Navigate to your local configuration directories: C:\ProgramData\Autodesk\CLM\LGS\ .

. If a previous analysis crashed but didn't release its license, ending these processes manually can free up the license for a new run. command line steps for manually resetting the license server address using the AdskLicensingInstHelper tool
