Add the installation directory (usually C:\Program Files\Autodesk\Moldflow... ) to your Antivirus exception list.
The causes of Error 99998 can be diverse, making it challenging to pinpoint a single reason. However, based on user reports and Autodesk support resources, some common causes include:
Autodesk Moldflow Error 99998 is a critical "Solver Abort" message. It indicates that the analysis engine has encountered a fatal mathematical instability or data inconsistency that prevents the simulation from continuing. Unlike specific warnings (e.g., "Element too thin"), the 99998 code is a generic crash code often accompanied by the message: "Solver aborted due to unknown error."
At its core, . The full message, as seen in the analysis log, typically reads: "Error 99998: Required license for [license type] is not available, or all licenses are currently in use or the product you have installed is not licensed to run this feature." The [license type] can vary, appearing as AMI_STANDARD , AMI_PREMIUM , AMI_ULTIMATE , or AMA_PREMIUM , depending on your product version and license tier. autodesk moldflow error 99998 best
Error 99998 on Linux requires a different set of solutions. The best approach depends on your specific installation.
If all the best fixes fail, you need a support ticket. Prepare these files:
2. Correct the License Server Configuration (2023 and Newer) For newer versions, licensing configuration has changed. However, based on user reports and Autodesk support
This critical error completely halts injection molding simulation workflows, disrupting plastic part design optimization. Because Moldflow relies on a decoupled architecture where the user interface ( Moldflow Synergy ) communicates via the Simulation Compute Manager (SCM) to check out a separate solver license ( Moldflow Insight ), even a minor misconfiguration can trigger this issue.
Before diving into complex reconfigurations, try these three initial steps. They often resolve the issue immediately without any advanced technical work.

In some network configurations, an analysis started on your computer might get pulled by another machine on the network, consuming a license elsewhere and causing the job on your machine to hang at 0% before failing with Error 99998. To fix this:
