The occurrence of Error 99998 can be attributed to several architectural and environmental factors within the Autodesk licensing ecosystem:

: The local machine has an empty or incorrect server hostname targeted within the software's network settings.

: The license may have expired, or the specific solver seat (e.g., MFIB, MFIP, or MFIA) is missing from the license file.

Given the range of potential causes, a systematic approach to troubleshooting is recommended. Here are several steps you can take to resolve the error:

systemctl status adsklicensing

– Switch to a different, well-known material from the same grade family. If the error disappears, the original material entry is corrupt (you may need to reinstall the material database).

Resolving this error requires systematic diagnosis. Start by verifying license configuration settings, ensure proper installation of licensing components, and check that license server information is correct. For Windows systems, the License Configuration utility is your primary tool. For Linux systems, focus on installing the licensing configuration package and setting correct environment variables. By following the steps in this guide, you should be able to restore normal operation and resume your mold flow simulations.
