The server managing the licenses is offline, or the client machine cannot reach it.
Many enterprises store Moldflow projects on network-attached storage (NAS) or Windows file servers. If the network experiences latency >10ms or packet loss, the lock negotiation fails. Moldflow's exclusive lock mechanism is sensitive to SMB (Server Message Block) protocol versions. Mismatched SMB versions (e.g., client using SMB 3.1.1, server limited to SMB 2.0) can cause false exclusive errors.
The solver attempts to pull a specific license tier (such as Moldflow Insight Ultimate) but finds the seat locked, or the Synergy interface fails to hand off the token exclusively to the localized solver thread. autodesk moldflow error 99998 exclusive
A full reboot clears all file handles held by the OS, removes temporary locks, and resets network connections. This solves ~30% of exclusive errors.
Open your Windows Start Menu and locate your specific Moldflow folder (e.g., ). The server managing the licenses is offline, or
The most common cause is a hung process. Even if Moldflow looks closed, the solver might still be running in the background. Open (Ctrl+Shift+Esc).
Ensure the , License Levels , and License Servers are correctly populated. Moldflow's exclusive lock mechanism is sensitive to SMB
Severely distorted tetrahedra, zero-thickness elements, or unconnected overlapping meshes can prevent the solver from generating the .mfl , .mf1 , .mf2 input files.
