Ensure that ports 2080 and 27000-27009 are open for Autodesk licensing communication.
Launch regedit.exe and navigate to the following registry branch: HKEY_CURRENT_USER\Software\FLEXlm License Manager Locate the key labeled ADSKFLEX_LICENSE_FILE .
If the network connection continues to fail, manually hardcode the path variables into the operating system. autodesk moldflow error 99998 full
The simulation log usually prints a variation of this string: ** ERROR 99998 ** Required license for AMI_STANDARD, AMI_PREMIUM, or AMI_ULTIMATE is not available, or all licenses are currently in use. The primary causes behind this error include:
Ensure the following TCP ports are open based on your version: : 44100, 44200 2021 : 43100, 43200 2017-2019 : 43911, 42911, 43921 Ensure that ports 2080 and 27000-27009 are open
Moldflow is an older codebase that still struggles with Windows’ legacy MAX_PATH limit (260 characters). If your project file path is too deep (e.g., C:\Users\JohnDoe\Desktop\Projects\ClientX\Moldflow\Rev15\HighResMesh\Study_5\Final_Attempt\ ), the solver will fail to create temporary files, leading to a buffer overflow (Error 99998).
A very specific error!
| Step | Action | What to look for | |------|--------|------------------| | 1 | Check free disk space on all drives | Less than 20GB free = red flag | | 2 | Check file path length | Count characters from C:\ to .sdy file. Over 200 = risky | | 3 | Verify .mfr file permissions | Right-click > Properties. Uncheck “Read-only” | | 4 | Review the solver log (.out file) | Look for lines with “Allocation failed” or “Buffer overrun” just above 99998 | | 5 | Run a mesh check (Mesh > Mesh Statistics) | Look for zero-volume elements or inverted normals | | 6 | Check Windows Page File settings | Control Panel > System > Advanced > Performance > Advanced > Virtual Memory |
