The is a critical licensing failure that prevents the solver from initiating an analysis. It occurs when the software cannot verify a valid license for the required tier, such as AMI_STANDARD , AMI_PREMIUM , or AMI_ULTIMATE . Core Causes of Error 99998
Because Moldflow decouples its user interface (Synergy) from its raw compute engine (Insight), a functional UI does not guarantee that the solver can check out its own distinct license token. Resolving this issue requires precise coordination between network configurations, the Autodesk Desktop Licensing Service (ADLS) , and FlexNet managers. 📋 Comprehensive Error Overview
Ensure that runflow.exe , gating.exe , and the Autodesk Simulation Job Manager executable are allowed through the Windows Defender Firewall for both private and public networks. 5. Update Graphics Drivers and Change Injection Settings
Ultimate Guide to Resolving Autodesk Moldflow Error 99998 indicates that the simulation engine cannot pull a required solver license to compute your plastic injection molding analysis . The error message typically reads: ** ERROR 99998 ** Required license for AMI_STANDARD, AMI_PREMIUM, or AMI_ULTIMATE is not available, or all licenses are currently in use . It happens because Moldflow separates its visual interface (Synergy) from its math solver engine (Insight), and the solver engine cannot communicate with your license system. autodesk moldflow error 99998 best
in your browser to verify that your machine is the only one listed in the "Location" column for your jobs.
Because this error terminates the analysis immediately, it requires systematic troubleshooting of mesh quality, boundary conditions, and material data to resolve.
Open your Windows Start Menu and find the Autodesk Moldflow Insight folder. The is a critical licensing failure that prevents
Whether you run Moldflow on Windows or Linux, this comprehensive technical guide compiles the absolute best industry practices, verified solutions from Autodesk Support documentation, and advanced diagnostic steps to permanently eliminate Error 99998 from your engineering environment. Direct Root Causes of Error 99998
This error appears across various versions of Moldflow, from older releases like 2021 to the latest versions. It affects both the Insight (solver) and Adviser (user interface) products, preventing you from running any analysis. Because it can be triggered by different reasons—on Windows, Linux, or in a network environment—there is no single fix. This article provides a systematic guide to resolve Error 99998, covering its most common causes and the best, most effective solutions for each scenario.
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: adopt the following workflow habits:
If the diagnostic test showed the error lies in the geometry:
If the server is on a different domain or reached via VPN, ensure the client can resolve the server's IP address and that firewall ports are open for the Autodesk Licensing Service .
If you have ever been ready to run a critical simulation only to be blocked by Error 99998 , you are not alone. This error specifically indicates that a
To avoid Error 99998 in future projects, adopt the following workflow habits:
