This is the most critical step and resolves the majority of cases. The License Configuration Utility ( mlc.exe ) must be run to point Moldflow to your license server.
Open and look for processes like flow.exe , cool.exe , or mhb3d.exe .
Security software is preventing the solver from communicating with the Network License Manager (LMTools) . Step-by-Step Fixes 1. Run the License Configuration Tool
: The Moldflow solver needs to know the location of the ALS service. This is done via the ADSK_SERVICE_ADDRESS variable.
: Ensure that the License Manager Tool (LMTools) is the most current version and that the license service is actively running. autodesk moldflow error 99998 full
This is the most common fix for Moldflow 2023 and newer versions. Close all Moldflow instances.
When pushing heavy batches or running Design of Experiments (DOE) sequences, the Simulation Compute Manager (SCM) can exceed local queue thresholds. If child jobs spawn faster than licenses release, the SCM drops trailing calculations with Error 99998. Detailed Troubleshooting Matrix
Confirm that you used the correct product keys during installation. Synergy (the UI) and Insight (the solver) use different keys.
: Ensure the SCM service is running and that your job limit hasn't exceeded your available licenses (each job consumes a license). Common Causes & Solutions Expired or Missing License This is the most critical step and resolves
A: No. This is strictly a CPU/memory/disk I/O error. Your GPU has nothing to do with it.
In the License Configuration window, verify that the , License Level (Standard, Premium, or Ultimate), and License Server Type are correct.
Modern versions utilize the to distribute and queue solving jobs. If the local caching directory corrupted or filled up, authentication requests time out before reaching the external network address. Installation & Key Mismatches
This article explores the primary causes of Error 99998 and provides step-by-step solutions to get your simulations back on track. Understanding Error 99998 This is done via the ADSK_SERVICE_ADDRESS variable
: The job queue is overloaded, or the local SCM service loses its tracking tokens.
Based on community experiences and Autodesk support documentation, we can approach troubleshooting by first understanding the system and then trying different fixes, starting with the most common cause.
Review the output array block. If the reported server attributes show missing ports, broken strings, or empty variables, clear and update the registration layer directly using the initialization directory scripts:
Under the terminal window, click New to create a custom global configuration instruction: Variable Name : FLEXLM_TIMEOUT
